java - 从服务启动第三方应用程序

Question

我需要从服务启动 Activity 。我尝试使用:

public void openApplication(String packageName){
      Intent intent = new Intent(packageName);
      intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
      this.startActivity(intent);
    }

但我得到这个错误:

E/AndroidRuntime(8563):android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.example.encrypted flg=0x10000000 }
04-30 11:55:07.507: E/AndroidRuntime(8563):     at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1765)
04-30 11:55:07.507: E/AndroidRuntime(8563):     at android.app.Instrumentation.execStartActivity(Instrumentation.java:1485)

有什么想法吗？

试试这个代码。您需要为程序包获取启动 Intent:

public void openApplication(String packageName) {
    PackageManager pm = getPackageManager();
    Intent intent = pm.getLaunchIntentForPackage(packageName);
    startActivity(intent);
}
