Question

我使用LeakCanary并且不幸得到了泄漏，这里是logcat：

这是我的DebuggingActivity

@Override
protected void onCreate(Bundle savedInstanceState) {
LeakCanary.install(getApplication());
setContentView(R.layout.activity_debugging);
activityTV = (TextView) findViewById(R.id.debugText);
LocalBroadcastManager.getInstance(getApplicationContext()).registerReceiver(screenReceiver, new IntentFilter("com.ponnex.justdrive.ActivityRecognitionIntentService"));

}
private BroadcastReceiver screenReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String activity = intent.getStringExtra("Activity");
        updateUI(activity);
    }
};

public static void updateUI(String activity) {
    activityTV.setText(activity);
}

我一直在检查我的活动并将其追踪，但我不知道如何解决这个问题？：d

如果您需要更多活动代码，我很乐意在此处添加或发布;）

--- --- EDIT

我还从另一项活动中泄漏了一些活动，指的是小吃吧（Snackbar by Nispok）

Answer 1

您需要调用LocalBroadcastManager.unregisterReceiver方法。

LocalBroadcastManager.getInstance(getApplicationContext()).unregisterReceiver(screenReceiver)

使用LeakCanary在AppCompatActivity上泄漏内存
