Timed out waiting for process to appear on device
You mentioned that restarting Android Studio didn't work for you...but it worked for me...
File > Invalidate Caches / Restart... > Just Restart
Android Studio 3.6.2
Build #AI-192.7142.36.36.6308749, built on March 18, 2020
For me, it took marking the build as "debuggable" in the application build.gradle
file.
For example:
android {
//...
buildTypes {
// ...
releaseStaging {
debuggable true // <- add this line
signingConfig signingConfigs.release
applicationIdSuffix ".releaseStaging"
versionNameSuffix "-STAGING"
matchingFallbacks = ['release']
}
}
}
Remember to remove this before building release APKs though!!!
There is a bug in the recent Android Studio release. You can revert to previous version or test it from command line.
