Android中在service中启动activity

启动activity：

Intent intent = new Intent(this,MainActivity.class);
startActivity(intent);

报错：android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

正确方式：

Intent intent = new Intent(this,MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);-----重要
startActivity(intent);

 

说明：启动的activity需要在AndroidManifest.xml中配置此activity的theme

<activity 
    android:name=".MainActivity"
    android:theme="@style/AppTheme"/>
