在Android上使用全局异常处理 [英] Using Global Exception Handling on android

问题描述

有没有代码示例，或有关如何使用Thread.setDefaultUncaughtExceptionHandler方法的教程？基本上，我在应用程序中尝试显示一个自定义警报对话框，无论何时抛出异常。有可能这样做吗？我知道在屏幕上显示某些东西有点棘手，如果在UI线程中抛出异常，但是我不知道这样做的任何工作。

解决方案

使用解决方案访问此页面的人的基本示例:)

  public class ChildActivity extends BaseActivity {
 @SuppressWarnings（unused）
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 int a = 1/0; 
} 
} 
  

处理错误的类：

  public class BaseActivity extends Activity {
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate savedInstanceState）; 
 Thread.setDefaultUncaughtExceptionHandler（new Thread.UncaughtExceptionHandler（）{
 @Override 
 public void uncaughtException（Thread paramThread，Throwable paramThrowable）{
 Log.e（Alert，Lets看看它是否工作!!!）; 
} 
}）; 
} 
} 
  

Is there a code example, or a tutorial on how to use the Thread.setDefaultUncaughtExceptionHandler method? Basically I'm trying to display a custom alert dialog, whenever an exception is thrown, in my application. Is it possible to do this? I know it's a little bit tricky to display something on the screen, if the exception is thrown in the UI thread but I don't know any work around for this.

解决方案

Basic Example for someone who comes to this page with a solution :)

public class ChildActivity extends BaseActivity {
    @SuppressWarnings("unused")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        int a=1/0;
    }
}

Class for handling error:

public class BaseActivity extends Activity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
         Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread paramThread, Throwable paramThrowable) {
                Log.e("Alert","Lets See if it Works !!!");
            }
        });
    }
}
