You can use StrictMode to catch mistakes earlier on in the development cycle. It’s especially useful for catching accidental disk or network I/O on the main thread.
Set up StrictMode in your Application’s onCreate().
if (BuildConfig.DEBUG) {
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectAll()
.penaltyLog()
.penaltyDeath()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectAll()
.penaltyLog()
.penaltyDeath()
.build());
}Consider developing with StrictMode set to detectAll()
