• 首先是在Application中實現介面

public class App extends Application {
//記得在清單檔案註冊App的name
    @Override
    public void onCreate() {
        super.onCreate();
        Thread.setDefaultUncaughtExceptionHandler(new MYExceptionHandler());
    }
    /**
     * 當app出現異常就會走下面的方法！！！
     * */
    class  MYExceptionHandler implements Thread.UncaughtExceptionHandler{

        @Override
 

        public void uncaughtException(Thread thread, Throwable throwable) {
            if (throwable != null) {
                final Writer result = new StringWriter();
                final PrintWriter printWriter = new PrintWriter(result);
                throwable.printStackTrace(printWriter);
                String errorReport = result.toString();
                Log.d("-<<<<>"
 
 , errorReport);

                //這裡吧errorReport post到http去就行了！！！
                //...

                 //或者儲存檔案到sd卡中          
                 saveInFile（errorReport ）;

                //最後殺死自己             android.os.Process.killProcess(android.os.Process.myPid());

            }
        }
    }
private
 
 void saveInFile(String errorReport) {
        FileOutputStream out = null ;

        File  file = new File(Environment.getExternalStorageDirectory() , "error-log.txt");
        if(Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())){
            try {
                out = new FileOutputStream(file);
                out.write(errorReport.getBytes());
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }finally {
                if (out != null) try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

• 我這個專案是如果異常了，就再次啟動自己

//在這個方法裡啟動另一個activity
 public void uncaughtException(Thread thread, Throwable ex) {
        if (ex != null) {
            final Writer result = new StringWriter();
            final PrintWriter printWriter = new PrintWriter(result);
            ex.printStackTrace(printWriter);
            String errorReport = result.toString();
            Log.d("-<<<<>" , errorReport); 

            //上傳http

            Intent intent = new Intent("com.dopool.devinstall.TwoActivity");
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.putExtra(CATCH_EXCEPTION, errorReport);
            mContent.startActivity(intent);
            android.os.Process.killProcess(android.os.Process.myPid());
