About StrictMode

Getting started

In your build.gradle:

 repositories {
    jcenter()
 }

 dependencies {
    debugCompile 'com.nshmura:strictmode-notifier:0.9.3'
    releaseCompile 'com.nshmura:strictmode-notifier-no-op:0.9.3'
 }

In your Application class:

public class ExampleApplication extends Application {

  @Override public void onCreate() {
    super.onCreate();
    
    if (BuildConfig.DEBUG) {
      //setup this library
      StrictModeNotifier.install(this);

      //setup StrictMode.
      // 
      // penaltyLog() should be called for strictmode-notifier
      //
      new Handler().post(new Runnable() {
        @Override public void run() {
          StrictMode.ThreadPolicy threadPolicy = new StrictMode.ThreadPolicy.Builder()
              .detectAll()
              .permitDiskReads()
              .permitDiskWrites()
              .penaltyLog() // Must!
              .build();
          StrictMode.setThreadPolicy(threadPolicy);

          StrictMode.VmPolicy vmPolicy = new StrictMode.VmPolicy.Builder()
              .detectAll()
              .penaltyLog() // Must!
              .build();
          StrictMode.setVmPolicy(vmPolicy);
        }
      });
    }
  }
}

How does it work?

  1. strictmode-notifier starts logcat command in backgound thread, and infinitely reads the log from logcat.
  2. If StrictMode violation is happend, error logs is outputed.
  3. strictmode-notifier reads that log via logcat, and shows a notification of the violation.

Customizing

How to ignore specific violations

StrictModeNotifier
    .install(context)
    .setIgnoreAction(new IgnoreAction() {
      @Override public boolean ignore(StrictModeViolation violation) {
        // ex) ignore LEAKED_CLOSABLE_OBJECTS that contains android.foo.bar in stacktrace.
        return violation.violationType == ViolationType.LEAKED_CLOSABLE_OBJECTS
            && violation.getStacktraceText().contains("android.foo.bar");
      }
    });

How to add custom actions

StrictModeNotifier
    .install(context)
    .addCustomAction(new CustomAction() {
      @Override public void onViolation(StrictModeViolation violation) {
        //ex) Send messages into Slack
      }
    });

How to disable Headup Notification

StrictModeNotifier
    .install(context)
    .setHeadupEnabled(false);
