I have been compiling QEMU 1.7.2 version for android ARM based device.
Currently I have been able to successfully emulate Windows XP using TCG (tiny code generator) present in QEMU for binary translation and hardware emulation as it is not using KVM (hw based acceleration).
I am facing difficulty in booting Windows 8 image in QEMU, and facing the below error.
Your PC needs to restart.
Please hold down the power button.
Error Code : 0x0000005D
Parameters:
0x03060303
0x756E6547
0X49656E69
0X6C65746E
........................................
the above experiment with windows is emulated on x86 based device emulation whereas actual device is an ARM based device.
So inorder to use KVM I need ARM based image of Windows OR combine the TCG binary translation part along with KVM Direct Execution which will utilise hardware acceleration.
Anyone has been able to use TCG and KVM together??
Thoughts on this will be very helpful..Please let me know if anyone has experimented.

Any progress on this? I would like to run qemu on android.

Hello!
I would like to ask about compiling existing C/C++/asm sourcecode on Android, specifically the code of the libav codec system. After that, I would like to statically link against it, and build the x264 commandline video encoder. I don't need any fancy GUI video encoding stuff, just the statically linked x264 cli tool. The libav is needed to be able to read H.264/AVC input, the x264 to encode somewhat similar H.264/AVC output.
I do have some experience in compiling that code on x86/x86_64 and MIPSEL (chinese Loongson-2f specifically) architectures in Linux with gcc/yasm, but I am a total noob, when it comes to cross-compiling unfortunately, I have only built the code sitting directly on the target system so far.
What I do have here, is a CentOS 6.0 x86_64 multilib Linux, GNU make and autoconf tools, latest Android SDK (probably not needed) and latest Android NDK toolchain (definitely needed) as well as the yasm assembler to build the ARMv7 assembler codepaths of libav and x264. I'm also able to fall back to pure C/C++ in case the asm stuff is impossible. I have found some guys having done the x264 alone using Google search, but info on how exactly they did it is quite scarce.
My primary target platform is Android 2.2 on a TI OMAP3 chipset with an ARM Cortex A8 processor that I believe has a hardware FPU, but no NEON SIMD extensions. I may also want to target slightly different hardware, but all using the ARMv7 instruction set basically.
So, if anyone has experience in cross-compiling libav/x264 or similar stuff like ffmpeg, I would greatly appreciate help in getting that done. At the moment I'm quite at a loss with cross-compiling using the NDK..
I hope I am posting in the correct subforum, it's my first post here. Thanks for any help you might be able to provide!!
Hi,
I have a program compiled for ARM Linux. It can use /dev/fb0 rather than X. Is there an Android app, possibly more than one choice, which will provide an environment where this program can run?
The version of this program for the Intel PC runs in Android under bochs. If the ARM executable can work, I'd expect it to be faster than the Intel executable.
Thanks! ... Peter E.
Hello,
I'm trying to set up virtualization within Android studio on my Lenovo Ideapad 320 with AMD A12-9720P processor and Windows 10 OS. Whenever I try to start a virtual phone in AS I get the message "Your CPU does not support required features (VT-x or SVM). I have tried and failed to install Intel HAXM from the sdk folder, getting a similar message about virtualization not being implemented. I have turned on virtualization in the BIOS (only AMD virtualization seems to be available) and disabling Hyper-V with "bcedit /set hypervisorlaunchtype off" from an elevated command prompt. Is there any other way to fix this, or can my computer simply not run android studio virtual phones? Thank you for any help provided.
My aims:
- Use Android Studio to develop a basic Android application - should be possible
- Use Android Studio to back up my physical phone (Hisense phone running Nougat 7.0) and create an emulated version of it running on my PC - should be possible, is it?
My PC:
- Windows XP 32-bit
- Pentium Dual Core T2330 processor NOT supporting Intel® Virtualization Technology (VT-x)
- 2 GB RAM
Questions:
- Are the above aims possible to achieve with my PC?
- If yes, what are the recommended Android Studio and Java SE Development Kit versions/settings to use that work for sure?
Story: I have tried to use Android Studio 3.0.1 with various versions of Java SE Development Kit 8 (including 121, 144, and 152) and various settings/hacks constantly running into various bugs/issues, most of which were seemingly resolved by new settings/hacks, yet I ended up with the same error messages after I have tried everything I have found online that nice people suggested on forums.
I am unable to even compile and run a default Android app, I get these error messages:
Gradle build finished with 2 error(s) in 21s 591ms
Error:java.util.concurrent.ExecutionException: java.lang.RuntimeException: No server to serve request. Check logs for details.
Error:Execution failed for task ':app:mergeDebugResources'.
> Error: java.util.concurrent.ExecutionException: java.lang.RuntimeException: No server to serve request. Check logs for details.
I am unable to run a default-loaded Android Virtual Device, I get this error message:
Emulator: Process finished with exit code -1073741511 (0xC0000139)
I am clueless how to continue. If my aims are possible to achieve, could someone tell me the Android Studio and JDK versions and settings that work 100% under 32-bit Win XP?
Thanks in advance!
I have a specific client request where there is a custom carried board which is controlled by a iMX8 SOM. On this board there is installed the Android system because there are specific Android applications (Java and Kotlin) which need to be run. I need to create a background service which controls specific IO peripherals (I2C, GPIOs, UART, etc...).
I suppose that in order to make a background (using the board IO peripherals) service which runs at the start of the Android OS system is to develop a C/C++ application (CMake based project) which will be cross compiled using a toolchain for the iMX8 and will be started at system boot through the "init.rc" script, right? Have you any available guide/material for such purpose so that I can begin with the best-practice solution?
I already tried using Android NDK, but I have "permission denied" errors also when installing the app in the "system/priv-app" folder (with the correct permissions).
Which is the correct way to approach this kind of project? Thank you.
