How to increase the font size of method trace view in Android Studio?

I figure out they just hardcoded font size to 8. So there is only a very weird solution with patching Android Studio jar files.

Steps:

1. Find /Applications/Android Studio.app/Contents/plugins/android/lib/sdk-tools.jar
2. Copy it somewhere else(do not forget to make a backup in case something goes wrong).
3. Unzip it and pick com/android/tools/perflib/vmtrace/viz/CallHierarchyRenderer.class
4. Take any hex editor and replace byte sequence 0504 4100 with 0504 4180 (actually, you replace 8 in class constant pool with 24)
5. Pack modified class back jar uf sdk-tools.jar com/android/tools/perflib/vmtrace/viz/CallHierarchyRenderer.class
6. Copy patched sdk-tools.jar back to its original location

You can try this one as an alternative to see flame graph of .trace file, it is pretty similar with call chart.

However, if you want to see call chart, you can modify source code on this repo by adding this command on the source code.

You can use this alternative android methods profiler/trace-viewer : https://github.com/Grigory-Rylov/android-methods-profiler

• it can resize font by 'ctrl' + '+'/'-'
• allows you add custom methods highlighting
• allows you to add custom bookmarks
• works much more faster than Android Studio profiler
• can easily record traces from the start, which is not always possible for another AS Profiler
• can open big trace files (400 Mb+)
