    }

    public  String

        return con.getFilesDir().getAbsolutePath()

    }

}

这是写一个类实现UncaughtExceptionHandler接口

然后在Application中创建他。

package cn.cmri.koudai.utilities.app;

import java.lang.Thread.UncaughtExceptionHandler;

import cn.cmri.koudai.utilities.tag.MyUncaughtExceptionHandler;

import android.app.Application;

public class BaseApplication extends Application
 {

    private static BaseApplication
 instance;

    @Override

    public void onCreate()
 {

        super.onCreate();

        instance
 = this;

        UncaughtExceptionHandler
 defaultUncaught = Thread.getDefaultUncaughtExceptionHandler();

        Thread.setDefaultUncaughtExceptionHandler(MyUncaughtExceptionHandler.getInstance(this,
 defaultUncaught));

    }

    public static BaseApplication
 getInstance(){

        return instance;

    }

}
