Android :: Emulator Not Booting With Customized Kernel Image
Oct 5, 2010
The emulator screen does not show up with new zImage... The steps I followed are: 1) Downloaded the android kernel from "git clone git://github.com/CyanogenMod/cm-kernel.git" 2) extracted config file from config.gz from /proc/config.gz in emulator 3) copied config file to .config in "cm-kernel" directory 4) export CCOMPILER=${HOME}/android/system/prebuilt/linux-x86/ toolchain/arm-eabi-4.4.0/bin/arm-eabi- 5) make ARCH=arm CROSS_COMPILE=$CCOMPILER oldconfig make ARCH=arm CROSS_COMPILE=$CCOMPILER menuconfig make ARCH=arm CROSS_COMPILE=$CCOMPILER

I want to create an application that loads an image as a map (a building of a floor) and add coordinates to it. Can anyone has an idea how to do it? I can do it maybe with MapView and change the resource of the map to my image but it is still not working.

I tries to modify the look of radiobutton: <style name="MyRadioButton" parent="android:Widget.CompoundButton.RadioButton"> <item name="android:textColor">#FF0000</item> <item name="android:background">@drawable/btn_radio</item> </style>
Android:background doesn't seem to be the right property, the radio button image gets stretched and placed in the background of the radio button itself and its label.

Sample code there is a method getitem(position) in the class of image adapter which returns null for the sample example. However, this method is important and is supposed to return the corresponding data item of the image adapter. For example the image adapter could generate a series of customized image views by magically calling the getview method. How could we implement the getitem(position) method under this case to help us gain access to these customized image views?

I just wrote a test app and deployed it via Google Api 2.2 emulator version 8. The emulator is running and the Android logo comes. But after that, no progress. When I checked the log, it shows a Mount Service with message 'waiting too long for ready! What should be done inorder to boot the emulator?

I had the 1.5 android emulator starting from Eclipse perfectly nicely.... until yesterday when it suddenly won't finish booting. I haven't installed anything new (Running it on Windows Vista - i know, uck, but I'm waiting for Win 7 to hurry up), haven't even changed the java code I am trying to run. The emulator starts up, get's to the point where it shows "Android" with the nice lighting effect that goes from left to right over it and then just stays in that state. Last night I tested it by starting it up, going out to the living room, watching two hour long episodes of the first series of Doctor Who, and then coming back in (Essentially giving it 1.5 hours to do it's stuff) - it was still stuck in that state. Any ideas what I did wrong?

I'm trying to compile omegamoon's kernel, it's a gitbub project.
I compiled it and I have the zImage.img. Using Finless ROM Flash Tool I flashed Finless 2.1 ROM, and works great. Then I flashed the same ROM but instead of the kernel that comes with that ROM I put my zImage there. As result my pen is not booting, and it's stuck in a black screen with two penguins..

Finally strace gave me this:
CODE:................
And several other attempts to call "link" that also fail (sshfs does not support hard links).
Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?

Has anyone successfully compiled the android kernel and tested it in the Android emulator, and if so is there anything that special that needs to be done? Documentation for the SDK is excellent, however documentation for compiling the kernel and setting up a custom machine in the emulator has been hard for me to find.

I recently started experimenting with the Android kernel. I downloaded the 3.0.31 kernel (because I wasn't able to find the sources for my stock one: 3.0.31-889555) and built a kernel image (zImage) successfully.
I plan to use Heimdall github.com/Benjamin-Dobell/Heimdall to flash the kernel image on my phone (Samsung Galaxy S2 GT-I9100) but before I do this I would like to download the current kernel image from my phone.
Since heimdall is capable to flash the current kernel image, I guess it's also capable of downloading the current, is it?

Is there any 1.5 image going around for the emulator? I would like to try my apps with onscreen keyboard. Maybe someone is actually making nightly builds but I can't find any.
PS: Not sure if it's appropriate to ask in this list.

As far as i know, Android emulator doesn't have a camera. To capture a live image we have to use the web camera. I have seen code in this web site to use the web camera in the android emulator to capture an image, but I don't know how to use this code.

I read about in the google documents that the 3 folders corresponds to different screen types and that android would select the image from different folders automatically according to the screen type. I read that WVGA will load from drawable-hdpi and HVGA will load from drawable-mdpi. When I tested with 2 emulators both running 2.1, each with HVGA and WVGA. It turns out that they are both reading the image in mdpi. If I deleted the image in mdpi then they read from hdpi. Can someone answer why emulator with WVGA is reading from drawable- mdpi?

Spent the whole day on this and still cannot find a solution for this. Here's my short code:
super.onCreate(savedInstanceState); setContentView(R.layout.videoview);
SurfaceView v = (SurfaceView) findViewById(R.id.surface_view);
holder = v.getHolder(); player = MediaPlayer.create(this, R.raw.psa);
player.setScreenOnWhilePlaying(true); player.setDisplay(holder);
try { player.start(); } catch(Exception e) { e.printStackTrace();}
The video itself is in raw directory. When the application starts I can hear the video's sound but no image is displayed. I've tried using 1.5, 2.0 and 2.1, same thing. I've tried this with different videos, tried converting them using ffmpegX and "Videora Android Converter", nothing helps.

I just download a cupcake branch of source code and build it. I configured Eclipse for a new SDK, and appear the things is works great, EXCEPT emulator. 1. I configured a new AVD as parameter i pointed my old sdcard.img then loaded and do not see my sdcard 2. then I back and configure another AVD with a parameter to create a new sdcard.img, when the emulator loaded I still not seen sdcard in emulator. 3. then I try to something like: emulator -avd myavd -sdcard mysdcard.img and there is still no sd card.
How can I restore my sd card in emulator.

I have seen a lot of posts about this, and it seems like the code below should work. I have created an SD Card image and added it to the emulator (and that works fine).
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
//intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1);
It does launch and allow selection of images, but when I click on an image, everything exits and the emulator returns to the home screen, not back to my app. My onActivityResult is never called either. What am I missing?

I'm using the android SDK in Eclipse on Linux. I've used the code at itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf to write an app to store an image captured through the camera onto SD card (there are various examples of this around). It works ok except that the image returned by the camera is not what's on the preview surface. Instead of getting the checkerboard image I expect, I get different versions of the android icon depending on which version of target I choose. If I render the image to an ImageView this is confirmed as it's the same as on the SD card.

I have a Nexus 4 which is bootloader unlocked and rooted. The USB port is partially faulty - it charges only at USB speed and is not detected as a device on my laptop. I've tried multiple cables, wall sockets and computers.
I do however have TWRP already installed.
Considering that fastboot from the PC is not an option (becase of the USB issue), can I run the fastboot commands inside the Terminal Command section of TWRP to flash a factory image of Android 4.3 ?
I'm asking because I've only seen guides to install recoveries, not ROMs via Terminal Command on phone.
