When I opened multiple pages/tabs on the Opera Mini 7.5, I pressed the home button to switch apps to see SMS, then returned to the Opera app by holding the Home button. Suddenly, my opened tabs were missing, just like opening a new tab. There is a task-killer application, but I can't remove it. This application has been installed as a default application in the Android phone. I was trying to delete some of the system apps, but there was no option saying "Delete" or "Uninstall". I also turned off all the Developer Options. How to keep the Opera Browser's tabs active when switching to another application? --- My phone info: - Model number: Device-01 - Android version: 2.3.6 - Baseband version: VENUS_BP_00.03.63.b501 - Kernel version: 2.6.38.6-perf zly @ HL120 # 1

Is there a way to list all Intents and all processes associated with them? Specifics: Droid X, 2.2 stock ROM, rooted. I'm perfectly fine with any approach, as long as it gets a guaranteed **complete** list: - A script or a series of commands in Terminal Emulator is fine. No limitation on supposed required technical proficiency (assume that the reader is a qualified long-term Unix power user). As noted, the phone is rooted. - An app is OK (ideally, it should be able to export the list, but even Autostarts-like GUI display is OK) Caveat: if you recommend an app (e.g. Autostarts ), I would request some assurance that it does, indeed, list **all** registered Intent receivers, not merely some sub-set - either as documentation/statement from the author or some other evidence (e.g. analysis of which APIs the code uses). - Worst case scenario, I'll take an API specifics

If I split the screen to see two apps, the splitting bar has huge rounded corners covering the apps. Below is a screenshot showing that. There, the bar covers parts of the video and parts of the search box. How do I disable the rounded corners? I have Poco F2 Pro with LineageOS 19.

I am a power user and I mostly switch a lot between apps, so I don't like discarding. I use a **custom ROM** which is less heavy than **MIUI ROM** yet Still my background apps take a lot of memory that multitasking without discarding is not possible even with 4GB + 2GB zRAM I have. Do you know any workaround for this without buying a new phone nor sacrificing apps, knowing that when I run cpuinfo in terminal: It doesn't show swp in features, so I don't think the **swap** will work out of the box with me and using a swap partition in my SD card will make the phone slow also except if there is a way to partition the internal storage or /data.

When I try to play music on Android 2.3 (using various players, including PowerAmp) on Sony Ericsson Xperia X10 I get not reliable sound. Music pauses for a short time, for example, when: * I press the power button (especially repeatedly) (request_suspend_state: sleep;request_suspend_state: wakeup in dmesg) * When I see messages like send sigkill to 15497 (ndroid.settings), adj 8, size 6428 in dmesg * When some program reacts to changed screen orientation. * When wifi connection gets established, when I force it to "reassociate" * When I go to/from application from home screen (AWDLauncher), except of to/from WidgetLocker screen. * When I enable/disable Airplane Mode. * When the display is off (the most annoying) When only really stable way to play music is to use StayAwake to force display on, turn off Wi-Fi, turn on Airplane Mode and don't switch applications. Starting CPU hogs like while true; do true; done does not affect chopping. And it was playing more or less fine on Android 2.1. "mediaserv" process (that writes to /dev/msm_pcm_out) has realtime io and scheduling priority, but sound is choppy anyway. If I start playing from console with mplayer -ao pcm:file=/dev/msm_pcm_out the sound chop less (notably it does not get interrupted by power button / loading bunches of heavy processes), but still behave not normally when screen is off (even ionice -c1 -p4 cat /dev/urandom > /dev/msm_pcm_out is choppy) When I start music A by usual way and music B using mplayer to /dev/msm_pcm_out (getting them mixed) music A chops more than usual and I usually hear B when A is in chop. When I turn off screen, both A and B chops in sync (stopping B leads to relatively more fluent playback of A this way). How to play music on Android reliably in presence of background load? Should I report a bug somewhere? Update Found a way of playing music. Inconvenient, but _without chopping_: 1. Start WakeLock in "CPU on, Screen Off, Keyboard off" mode 2. Use mplayer to play music bypassing Android: ionice -c1 -n4 \ schedtool -R -p 3 -e \ mplayer -really-quiet \ -af volume=-26 -quiet \ -ao pcm:file=/dev/msm_pcm_out,nowaveheader \ /mnt/sdcard/music/something.ogg # (created script to start it easily, of course) Plays without chopping no matter how much applications I start, what do with Wifi, orientation and airplane modes. Even with "powersave" cpufreq governor (everything very slow, but music plays fine). So the hardware have enough resources to play it. Update 2 Looks like doing for i in pgrep ''; do schedtool -D $i; done i.e. "Set Idle priority for all processes" makes music play fine even when I {start programs,lock screen,rotate screen;it reconnects to other mobile network stations} at expense of some input lag in games. Don't know exactly why it happens.

Is there a way to play sound from any two apps (or more) simultaneously on Android? For example I have Audible reading a book. I'd like to play sound from a relaxation app at the same time. Or from my music collection.

I noticed that on my Xiaomi 11i with the Snapdragon 888 processor, it is supposed to be one of the current top Android phones, with 8 cores and that only the Apple A14 Bionic has slightly higher performance than it. However, if I run two Pokemon Go using its Dual App split screen, then I noticed, if we look inside a gym, and a Pokemon (Venonat or Exeggutor) is swinging left and right, then every few seconds, on the top or bottom screen, the Pokemon would have a slight 0.2 second pause, so both apps are choppy every few seconds. If I use the app Activity Monitor, right after I boot up the phone so that no other app is running, I did see that every 6 to 10 seconds, all the cores of the processors would ramped up to 100%, so it looks like it is doing some work in the background. I noticed if I run one single instance of Pokemon Go, then it is smoother. But my question is, how can 8 cores not able to handle some slowing animating graphics. If anything, the swinging left and right repeatedly can even be "set it and forget it" -- everything done by the GPU (Adreno 660). So trying to solve it, I tried to tap the Version number of the system for a few times and went to Developer's Options, and from there, I set the background app to be: Running only 1 process at a time. So that should mean I have 7 cores running now for the 2 apps on screen? But after rebooting the phone and trying again, the same issue was still there. Is there a way to make it able to take 2 cores (or 3 cores) for each app, or just make them run at top performance and let any background process run with the remaining 2 cores? Or another way is, if there is a way to set the background processes only use up to 50% of the cores, so the main apps can always have 8 cores to use. **Update:** an insight to finding a solution: I noticed if we tap on a Pokemon and try to catch it, the Pokemon, if it is a flying Pokemon with their wings constantly flapping in the dual app, has really smooth animation and there is no tiny pauses ever. It may appear that when we look inside of a gym, usually six Pokemon are shown inside, so if both apps are looking inside of a gym, there can be 12 Pokemon moving inside. Even if 10 Pokemon have tiny movements only and two Pokemon have more apparent movements, it seemed it was possible that 12 threads were used, and so if there are 12 threads and 8 cores, maybe that's the reason that there can be tiny pauses. I am not sure if we can change the Settings on the phone to solve this, as these movements are very lightweight.

With its multi-tasking, it's easy to launch lots of applications on Android. I understand that background applications use fairly minimal resources, but they often activate features (GPS WiFi etc.) that drain the battery. How can you find out what applications are running and what resources they're using? and how can you stop them safely?

I'm using an Android 10 Samsung device that supports multitasking using pop-up windows. I'm trying to type on the main window with a YouTube window in the foreground. The keyboard keeps closing whenever I use the YouTube pop-up. Is there any way to keep it open? 

I have a Xiaomi Mi Pad 4 tablet, on a custom ROM (Floko), including Magisk and root. Today decided to update to Android 10. I can't find a way to make multitasking feel good again. The new app switchers put only 1 app per screen and give mile-long scroll distances to the others. The old Oreo fallback has been removed from AOSP. [\[1\]][1] (It stacked apps vertically, with their titles - you had access to 4/5 apps on the same screen.) My rom has the option to use OmniSwitch recents, which put more apps on the same screen, but they disable the double-tap to previous app functionality. Also not the best recebts UI (though way ahead of the newer ones). Semi-related: The pixel launcher puts some icons down in the recents based on I don't know what logic, but even those get obliterated when I switch launchers. And I want to switch launchers badly, because the pixel launcher doesn't let me manage home screens. Any way to make app switching good again (rom or app)? I'd rather not downgrade, cuz the Pie rom had some other issues with my device (Which might end up worth it, given how frequently I end up app-switching and what a horrible experience it is now.)

If I'm seeing a video on YouTube app, a website in Chrome, Firefox or checking some thread in Stack Exchange app and I minimize the app to open another app or go to home, then I return to previous app happens that automatically is refreshing the app (Youtube, Chrome, Stack Exchange or any other). For example, if I'm seeing a video for 5 minutes, go to another app and then return to YouTube, automatically loads the same video but from the beginning, not in minute I stopped it. The phone where this undesired refreshing happens is Huawei and has Android 9 and EMUI 9.1.0. Another phone with Android 7.1 that is not Huawei and doesn't have EMUI, for example, doesn't make this kind of refreshing. Is there a configuration option to stop this refreshing? Thanks in advance.

It is said that with MIUI, it is possible to run the same app twice as if they are on two different phones. (example: WeChat or Line running with a work account and one running with a personal account). Is it possible to run the same app twice, and side by side on an Xiaomi Redmi 4X with MIUI 8? Or is it only possible to show them one at a time? If it is only possible to show one at a time, you can't really play some games such as Pokemon Go and do the Raid Battle at the same time using both accounts (since you have to switch screen to one at a time and therefore not play at the same time). And if it is possible side by side, can it be vertically or horizontally split on the screen, but won't the 2 apps be really small and make it not practical to play at the same time? Could some screenshot / YouTube video be posted if you are possible to make it happen?

Is there any way to run more than 2 apps side by side? Preferably on a Mi Pad 4 tablet in landscape. I'm only really looking towards a Xiaomi device since Miui allows input to both apps simultaneously when in split screen, with other devices you need to press on an app to select it and then are able to input, the window that's not selected gets suspended, if that makes any sense.

I have searched for a way to enable free form windows. I've used the adb way, adb shell settings put global enable_freeform_support 1 But I couldn't use it because the close button is overlapping free form button: My phone is Huawei P20 Lite (ANE-LX1) with EMUI 8.0.0 and android 8.0.0 with nova launcher. Close button works like a charm when clicked Any ideas what to do (rather than disabling the free form ) ? It is okay to replace closing button with free form button if that's available. Any solution without root is preferred.

I have a Samsung Galaxy S (AT&T Captivate) that is rooted. I have various ways to tweak the amount of free RAM the OS leaves on the phone. The default is 48 MB, but I was wondering if I could actually go lower without impacting phone performance. Are there guidelines posted anywhere, or that can be deduced based on knowledge of the Android platform? Or should I trust that the default settings are appropriate? I understand that when it comes to free RAM, more isn't necessarily better, but I understand that there is still a threshold that I don't want to dip below. I'm running a 2.3.6 Gingerbread based ROM. For what it's worth, I'm running the Zeam launcher.

I use split screen YouTube and Chrome on my phone, but when I visit e.g. bbc.com the video volume fades to a much lower level. What causes this and can it be prevented? This is a OP3t with Android 8.0 in case that matters

I am trying to run 2 apps in split screen with both staying active at the same time. Most results on google are saying this is not possible and they blame the app for it not working. Below is some detailed testing I have done. This is an android issue/setting, not an app issue. The reason I know this is because I have 2 phones both using split screen. One can/will/does keep *both* apps active at the same time while one pauses whichever one is not in focus. The apps are identical across both phones. - **Apps for testing:** Pokemon Go (Pogo) + Jurassic World Alive (JWA) (both AR games that use GPS and real time location constantly). - **Phones for testing**: Moto X4 and Xiaomi Redmi 5 Plus (I have previously tested on the Axon 7 and the Nexus 4-5-6, both behave the same as the Moto X4 currently does). - **Android versions:** Redmi5 - Android 7.1.2 (MIUI 9.6.2.0) | Moto X4 - Android 8.1.0 - **One item of note:** On the Moto I had to enable developer mode and turn on 'Force activities to be resizable' before either app could be put into split screen. On the Redmi5 this was not needed as it was already enabled. - **Test method:** Open Pogo normally. Use the 'intents' (app switch) button and at top click the section titled "split screen" (both phones have slightly diff wording here). Drag Pogo up there and it takes up the top half of the screen. In the bottom section, select previously running JWA (or start it from home screen) and it will take up the bottom section of the screen. - **Wanted outcome (Redmi 5 Plus):** Top portion continues without pausing and bottom game loads and works without pausing. Both apps continue to run as if they were running in full screen and were active - **Unwanted outcome (Moto X4/Axon7/Nexus(4|5|6):** Top app freezes or pauses when you load the bottom app. To unpause it, click on it, but this pauses the bottom app. Whichever app was last clicked on is active. Since the apps I am using to test are identical across 3 of the phones I am testing (never tested JWA on the nexus phones) this cannot simply be an issue with the apps not supporting it. There has to be some setting that Xiaomi or MIUI enabled to allow this to work. Another note, I am not trying to get *only* these 2 apps working, but these are 2 I would like to have working and made for good test apps due to how they run. I realize my ask here may be unclear. *I want to know how to duplicate the functionality from the Redmi 5 Plus on my other devices (Moto X4, etc).* **'Duplicate' edit:** I do not feel like the question listed as duplicate answers mine other than "you cant", but obviously MIUI or Xiaomi did. Also that answer seems to point to some side effects I should be experiencing on my Redmi that I am not (apps not pausing when minimized/unfocused).

I'm thinking that with the way we typically use Android phones, run a single app at a time, fewer faster CPU cores are better than many smaller (slower) cores. Does Android really benefit that much from the current octa-core phones? How long before we see 16-core Android phones, and will that actually be useful in a phone? I keep thinking that 4 fast cores, or 2 very fast cores, seem ideal for the kind of things we do with Android phones. Is it possible to determine some ideal number of cores, or at what point it simply does not make sense to add more cores?

I'm looking to get an Android tablet and I'd like it to support running two apps on the screen at a the same time; what is the earliest release of Android to support this?

I have a 10 inch Nexus tablet that I like to carry around while traveling. I can also connect it to a bluetooth keyboard, and this almost allows me to do everything a laptop can, but there are some major annoyances. For example, I want to do web development while traveling. I can SSH into a remote server and edit the code there, and open the page on the Chrome app. However, Android only lets me have one app open at a time, so whenever I need to switch between two documents, it's very inefficient since I'm constantly closing and re-opening my apps. I would like to use my Nexus 10 as my primary computer for working. How can my multitasking experience be improved?
