Question

我想从启动器中消失我的应用程序图标，应用程序会在一段时间后自动重启。我在下面隐藏了图标代码：

 try {
       PackageManager p = context.getPackageManager();
        ComponentName componentName = new ComponentName("com.package.name", "com.class.name");
        p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
    } catch (Exception e) {
        Log.d("ERROR@@", "" + e.toString());
    }

这是一段时间后重新打开我的应用的代码

public void initializingTimerTask() {
    timerTask = new TimerTask() {
        @Override
        public void run() {
            mHandler.post(new Runnable() {
                @Override
                public void run() {
                    if (mIsInForegroundMode == false) {
                        Intent LaunchIntent=getPackageManager().getLaunchIntentForPackage("com.package.name");
                        LaunchIntent.setFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS | Intent.FLAG_ACTIVITY_NEW_TASK);
                        startActivity(LaunchIntent);
                    } else {
                    }
                }
            });
        }
    };
}

错误：

但是当转向重启应用程序应用程序崩溃时，请帮助我。

如果我理解正确而不是在这里。要隐藏图标，请使用以下命令：

PackageManager p = getPackageManager();
    ComponentName componentName = new ComponentName(this, com.sstudio.sysUtil.TheActivity.class); // activity which is first time open in manifiest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
    p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

请记住，在再次打开应用程序之前，您需要首先取消隐藏图标，然后打开应用程序，否则它将崩溃。这样做：

PackageManager p = context.getPackageManager();
        ComponentName componentName = new ComponentName(context, TheActivity.class);
        p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); // to unhide the icon and to prevent the app from crashing
        Intent i = new Intent(context, TheActivity.class);// use your own intent as required
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);// and add flags as required
        context.startActivity(i);//and open activity

我遇到了同样的问题。这确实解决了我的问题希望它也能解决你的问题。

修改改变你的代码：

public void initializingTimerTask() { timerTask = new TimerTask() { @Override public void run() { mHandler.post(new Runnable() { @Override public void run() { if (mIsInForegroundMode == false) { Intent LaunchIntent=getPackageManager().getLaunchIntentForPackage("com.package.name"); LaunchIntent.setFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS | Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(LaunchIntent); } else { } } }); } };}

用这个：

public void initializingTimerTask() { timerTask = new TimerTask() { @Override public void run() { mHandler.post(new Runnable() { @Override public void run() { if (mIsInForegroundMode == false) { PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(getApplicationContext(), TheActivity.class); p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); Intent LaunchIntent=getPackageManager().getLaunchIntentForPackage("com.package.name"); LaunchIntent.setFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS | Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(LaunchIntent); } else { } } }); } };}
