Error when trying to use Android systrace.py on Linux Ubuntu
android,python,linux,adb,systrace
I fixed the issues by changing my PATH export to be specified by absolute path instead of relative path. This means, I can't define my home directory using ~/..., I have to use /home/username/.... export PATH="/home/user1/Applications/android-studio/bin/:$PATH" export PATH="/home/user1/Android/Sdk/platform-tools/:$PATH" export PATH="/home/user1/Android/Sdk/tools/:$PATH" However, it is not clear to me why systrace.py won't...
“Enable traces” is missing in Developer options android
The "enable traces" debugging option was not introduced until Android 4.1. You'll need to use a different device to use this option.
Getting BufferQueue state in systrace
android,vsync,systrace,surfaceflinger
The BufferQueue information is available in systrace/atrace/ftrace, with a few caveats. In the traces you might see SurfaceView debug information; this will show you the BufferQueue state (but only if a SurfaceView is being used!). Binder_4-1188 ( 171) [000] ...1 12563.059605: tracing_mark_write: C|171|SurfaceView|1 In this case, BufferQueue = 1 If...
Write output of android shell command to a file
android,android-manifest,file-handling,systrace
I solved it by reading data from inputstream and writing it to a file try { Process p = Runtime.getRuntime().exec("atrace -t 5 gfx"); p.waitFor(); BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream())); String line = reader.readLine(); File myFile = new File("/storage/sdcard0/trac.txt"); FileOutputStream f = null; try { f = new FileOutputStream(myFile); }...
Is logging Android systrace events directly from native code possible, without JNI?
android,c,android-ndk,tracing,systrace
I don't think it's exposed from the NDK. If you look at the sources, you can see that the android.os.Trace class calls into native code to do the actual work. That code calls atrace_begin() and atrace_end(), which are declared in a header in the cutils library. You may be able...
Android triple buffering - expected behavior?
The amount of buffering provided only matters if you keep the buffers full. That means rendering faster than the display is consuming them. The labels don't appear in your images, but I'm guessing that the purple row above the green vsync row is the BufferQueue status. You can see that...
Can you use the Android Trace class from multiple threads?
It's safe. It writes a marker to the systrace device, which is shared across multiple processes and threads.
Android Systrace: Unexpected error (Conversion = ';')
I finally fixed my issue following @fadden's guidance in the comments. I used the command prompt to find out what my issues were, but my problem was also fixed for the GUI. Here's how I did it: First, install Python if it's not already installed. I reinstalled it selecting the...
