Android(安卓)全局异常上报

开始实现
1、实现Thread.UncaughtExceptionHandler接口

public class ExceptionHelper implements Thread.UncaughtExceptionHandler {    @Override    public void uncaughtException(Thread t, Throwable e) {            }}

2、单例模式

private static volatile ExceptionHelper INSTANCE;private ExceptionHelper() {}public static ExceptionHelper getInstance() {    if (INSTANCE == null) {        synchronized (ExceptionHelper.class) {            if (INSTANCE == null) {                synchronized (ExceptionHelper.class) {                    INSTANCE = new ExceptionHelper();                }            }        }    }    return INSTANCE;}

3、初始化异常信息

private Thread.UncaughtExceptionHandler mDefaultHandler;public void init() {    // 获取默认异常处理器    mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();    // 将当前类设为默认异常处理器    Thread.setDefaultUncaughtExceptionHandler(this);}

4、捕获异常

@Overridepublic void uncaughtException(Thread t, Throwable e) {    if (handlerException(e)) {        // 未处理异常，调用系统方法来进行处理，弹出错误弹框或闪退        if (mDefaultHandler != null) {            mDefaultHandler.uncaughtException(t, e);        }    } else {        // 拦截错误，可进行重启APP等后续操作    }}private boolean handleException(Throwable e) {    if (e == null) {        return false;    }    Writer writer = new StringWriter();    PrintWriter pw = new PrintWriter(writer);    e.printStackTrace(pw);    pw.close();    String result = writer.toString();    Log.e("TAG", result);    return true;}

5、在App中初始化

public class App extends Application {    private static Context mContext;    @Override    public void onCreate() {        super.onCreate();        mContext = getApplicationContext();        // 初始化ExceptionHelper        ExceptionHelper.getInstance().init();    }    public static Context getContext() {        return mContext;    }}

测试

 在启动Activity中调用 int a = 1 / 0。APP没有闪退，也没有弹出错误提示。收集到的错误日志如下：E/TAG:java.lang.ArithmeticException: divide by zero    at com.lbj.mvpflower.mvp.ui.activity.UserActivity.onUser(UserActivity.java:36)    at java.lang.reflect.Method.invoke(Native Method)     at android.view.View$DeclaredOnClickListener.onClick(View.java:4702)     at android.view.View.performClick(View.java:5619)     at android.view.View$PerformClick.run(View.java:22298)     at android.os.Handler.handleCallback(Handler.java:754)     at android.os.Handler.dispatchMessage(Handler.java:95)     at android.os.Looper.loop(Looper.java:165)     at android.app.ActivityThread.main(ActivityThread.java:6365)
