在我的应用程序中，我使用全局异常处理程序来避免强制关闭。但是在调用system.exit（0）之后启动了一个活动.... ????
显示的logcat是：

稍微迟来的答案，但是...在我的情况下，这只发生在少数设备上，例如三星Nexus 7.为了避免这种恼人的重启，我记得静态变量中的当前活动并在{finish()之前调用System.exit 1}}：
// base class for all activities in my application
class BaseActivity extends Activity {
private static BaseActivity sCurrentActivity = null;
@Override
protected void onCreate( Bundle savedInstanceState ) {
super.onCreate( savedInstanceState );
sCurrentActivity = this;
}
@Override
protected void onStart() {
super.onStart();
sCurrentActivity = this;
}
@Override
protected void onResume() {
super.onResume();
sCurrentActivity = this;
}
@Override
protected void onPause() {
super.onPause();
sCurrentActivity = null;
}
public static System_exit( int exitCode ) {
if ( null != sCurrentActivity ) {
sCurrentActivity.finish();
sCurrentActivity = null;
}
System.exit( exitCode );
}
}
答案 1 :(得分：1)
谢谢！这很有效 - 但是：你必须完成你的主要活动，如果你完成了其他的活动，它就无法工作。 这里有一些增强功能：如果你想要一个活动的静态引用，你最好使用弱引用和静态getter，而不是强引用：
public class MainActivity extends Activity {
private static WeakReference<MainActivity> sharedActivity = null;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sharedActivity = new WeakReference<MainActivity>(this);
setContentView(R.layout.activity_main);
}
public static MainActivity sharedActivity() {
try {
return sharedActivity.get();
} catch (Exception e) {
return null;
}
}
}
WeakReference不会阻止垃圾收集器对GC进行活动。如果收集它，WeakReference的返回值将为null，否则返回活动对象。它简化了代码并阻止您访问已完成的活动。
