如何清理资源,以防我的安卓应用程序崩溃或手动杀死?

对于force kill,我不确定,但在崩溃的情况下,您可以删除以下数据:

unCaughtException

 public class MyExceptionHandler implements
            java.lang.Thread.UncaughtExceptionHandler {
        private final Context myContext;
        private final Class<?> myActivityClass;

        public MyExceptionHandler(Context context, Class<?> c) {

            myContext = context;
            myActivityClass = c;
        }

        public void uncaughtException(Thread thread, Throwable exception) {

            //delete your data
        }
    }

在每个活动中创建一个此类的对象并将其设置为 DefaultUncaughtExceptionHandler

Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this,
            YourCurrentActivity.class));

在最近的酒吧里杀死了应用程序: onDestryoy() 方法被调用。

public void onDestroy(){ 
  super.onDestroy(); 
  // delete you data here
}

为了 ANR(Application Not Responding) 或 crash 您应该使用:

 public class MyExceptionHandler implements
        java.lang.Thread.UncaughtExceptionHandler {
    private final Context myContext;
    private final Class<?> myActivityClass;

    public MyExceptionHandler(Context context, Class<?> c) {

        myContext = context;
        myActivityClass = c;
    }

    public void uncaughtException(Thread thread, Throwable exception) {

        //delete your data
    }
}

在每个活动中创建一个此类的对象并将其设置为 DefaultUncaughtExceptionHandler

Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this,
            YourCurrentActivity.class));

将删除代码放入以下方法:

public void onDestroy() { super.onDestroy(); }
