安卓：拋出：IllegalArgumentException： 「Component類X不存在」 在API 17（不崩潰API 8）

Question

我的模擬器：

當我推出的平板模擬器我得到：

當我啓動升級Froyo模擬器所有的罰款（編輯：不，沒有 - 接收器未啓用，但仍然沒有崩潰）。
這是一個已知的問題或什麼？

清單：

private static void enable(Context context, boolean enable, String className) { 
    PackageManager pacman = context.getPackageManager(); 
    final ComponentName componentName = new ComponentName(context, className); 
    final int state = (enable) ? PackageManager.COMPONENT_ENABLED_STATE_ENABLED 
      : PackageManager.COMPONENT_ENABLED_STATE_DISABLED; 
    pacman.setComponentEnabledSetting(componentName, state, // line 81 
      PackageManager.DONT_KILL_APP); 
} 

public static void enable(Context baseContext, boolean enable) { 
    enable(baseContext, enable,     // line 86 
      TriggerMonitoringBootReceiver.class.getSimpleName()); 
} 

而且在SettingsActivity：

@Override 
public void onSharedPreferenceChanged(SharedPreferences sp, String key) { 
    if (MASTER_ENABLE.equals(key)) { 
     TriggerMonitoringBootReceiver.enable(getBaseContext(),  // line 192 
       sp.getBoolean(key, false)); 
     Toast.makeText(getApplicationContext(), 
       "CB: " + sp.getBoolean(key, false), Toast.LENGTH_SHORT) 
       .show(); 
    } 
}

編輯：現在都清楚，使用ComponentName(Context pkg, Class<?> cls) - 作爲在API的區別：
Calls to PackageManager.setComponentEnabledSetting will now throw an IllegalArgumentException if the given component class name does not exist in the application's manifest.

Answer 1

TriggerMonitoringBootReceiver.class.getSimpleName(); 

和打包

PackageManager pacman = context.getPackageManager(); 

一起給

di.k23b.hw3.TriggerMonitoringBootReceiver 

因此，您缺少類名稱中的「/ receivers /」文件夾前綴

Answer 2

如果使用AndroidAnnotations，請改用覆蓋類名稱。

// CORRECT class definition. 
ComponentName receiver = new ComponentName(context, NotificationPublisher_.class); 

但是，

// THIS WILL GIVE YOU CRASH. 
ComponentName receiver = new ComponentName(context, NotificationPublisher.class); 

Answer 3

就在這個線程已經彙總的信息。

使用構造函數 ComponentName(Context pkg, Class<?> cls)。

此外，組件名稱需要在清單中指定。請參閱this link中的JELLYBEAN。
Calls to PackageManager.setComponentEnabledSetting will now throw an IllegalArgumentException if the given component class name does not exist in the application's manifest.
