全局异常捕获

java代码：

package com.gy.my;

import android.content.Context;
import android.os.Looper;
import android.util.Log;
import android.widget.Toast;

public class CrashHandler implements Thread.UncaughtExceptionHandler {
    public static final String TAG="CrashHandler";
    private static CrashHandler mInstance;

     //系统默认UncaughtExceptionHandler

    private Thread.UncaughtExceptionHandler mDefaultHandler;
    private Context mContext;
     //*获取CrashHandler实例
    public static synchronized CrashHandler getInstance() {
        if (null == mInstance) {
            mInstance = new CrashHandler();
        }
        return mInstance;
    }
    public void init(Context context) {
        mContext = context;
        mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();
        //设置该CrashHandler为系统默认的
        Thread.setDefaultUncaughtExceptionHandler(this);
    }
    @Override
    public void uncaughtException(Thread t, Throwable e) {
        //自己处理
        if (!handleException(e) && mDefaultHandler != null) {
            //如果自己没处理交给系统处理
            mDefaultHandler.uncaughtException(t, e);
        } else {
            try {//延迟3秒杀进程
                Thread.sleep(2000);
            } catch (InterruptedException es) {
                Log.e(TAG, "error : ", es);
            }
        }
    }
    /**
     * 收集错误信息.发送到服务器
     *
     * @return 处理了该异常返回true, 否则false
     */
    private boolean handleException(Throwable ex) {
        if (ex == null) {
            return false;
        }
        //添加自定义信息
        addCustomInfo();
        //使用Toast来显示异常信息
        new Thread() {
            @Override
            public void run() {
                Looper.prepare();
                //在此处处理出现异常的情况
                Toast.makeText(mContext, "程序开小差了呢..", Toast.LENGTH_SHORT).show();
                Looper.loop();
            }
        }.start();
        return true;
    }
    /**
     * 添加自定义参数
     */
    private void addCustomInfo() {
        Log.i(TAG, "addCustomInfo: 程序出错了...");
    }



}

MyApp.java

package com.gy.my.app;

import android.app.Application;

import com.gy.my.CrashHandler;
import com.umeng.commonsdk.UMConfigure;
import com.umeng.socialize.PlatformConfig;

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        CrashHandler.getInstance().init(this);//全局异常捕获
    }
       
}

最后别忘了在清单文件中注册Myapp
