Android應用崩潰后異常捕獲并重啟

    public class MyApplication extends Application implements

            Thread.UncaughtExceptionHandler {

        @Override

        public void onCreate() {

            super.onCreate();

            //設置Thread Exception Handler

            Thread.setDefaultUncaughtExceptionHandler(this);

        }


    @Override  
    public void uncaughtException(Thread thread, Throwable ex) {  
        System.out.println("uncaughtException");  
        System.exit(0);  
        Intent intent = new Intent(this, MainActivity.class);  
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |  
        Intent.FLAG_ACTIVITY_NEW_TASK);  
        startActivity(intent);  
    }  

}  </pre></b><span style="font-family:Comic Sans MS;font-size:18px;">最后需要在Manifest中配置Application的標簽<span class="s1">android:name</span><span class="s2">=</span>".MyApplication"，讓整個應用程序使用我們自定義的Application類，這樣就實現了當應用遇到崩潰異常時重啟應用的效果。</span> <p class="p1"><span style="font-family:Comic Sans MS;font-size:18px;">我們在任意一個Activity中主動拋出下面異常，就會發現應用遇到異常后重啟了，如果不處理的話，應用在遇到異常后就關閉了。<pre class="brush:java; toolbar: true; auto-links: false;">    throw new NullPointerException();  </pre></span> <p></p>
