OwlMonitor 猫头鹰监控

OwlMonitor is an analysis tool for detecting Android UI block.

1. Detect ui frame refresh block.
2. Detects the timeout operation of the main thread Looper.
3. The main thread block outputs the simple stacktrace information.
4. Customize the processing of block output information, such as log output, reporting background and so on.
5. Support in the background to stop monitoring, reduce power consumption, the background call pause (), the front desk call resume ().

Sample

public class MainApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        OwlMonitor.instance().start(new OwlMonitorCallback() {
            @Override
            public void onSkippedUIFrames(long skippedFrames, long skippedDurationMs) {
                Log.i(TAG, String.format("onSkippedUIFrames frame:%d duration:%d ms", skippedFrames, skippedDurationMs));
            }

            @Override
            public void onBlockMainThread(long blockDurationMs) {
                Log.i(TAG, String.format("onBlockMainThread block:%d ms", blockDurationMs));
            }

            @Override
            public void onBlockTrace(String stack) {
                Log.i(TAG, String.format("onBlockTrace stack:%s", stack));

            }
        });

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            registerActivityLifecycleCallbacks(mCallback);
        }
    }
    
    private ActivityLifecycleCallbacks mCallback = new ActivityLifecycleCallbacks() {
        @Override
        public void onActivityCreated(Activity activity, Bundle savedInstanceState) {

        }

        @Override
        public void onActivityStarted(Activity activity) {
            OwlMonitor.instance().resume();
        }

        @Override
        public void onActivityResumed(Activity activity) {
        }

        @Override
        public void onActivityPaused(Activity activity) {
        }

        @Override
        public void onActivityStopped(Activity activity) {
            OwlMonitor.instance().pause();
        }

        @Override
        public void onActivitySaveInstanceState(Activity activity, Bundle outState) {

        }

        @Override
        public void onActivityDestroyed(Activity activity) {

        }
    };
}

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

dependencies {
    compile 'com.github.itvincent-git:owlmonitor:1.0.0'
}
