Android借助Application重写App的Crash(完整版)

MainActivity如下:

[java]
package cn.testcrash;
import android.app.Activity;
import android.os.Bundle;
/**
* Demo描述:
* 借助于Application自定义Crash
*
* 备注说明:
* 1 在获取Crash信息后可依据业务上传服务器或者保存至SDCard
* 2 在uncaughtException()中的第三步——退出程序.此处只是做了
*   最简单的处理.完备的操作请参见:

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        init();
    }
    //Crash
    private void init(){
        System.out.println((9727/0)+"");
    }
}

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  init();
}
//Crash
private void init(){
  System.out.println((9727/0)+"");
}
}

CrashApplication如下:

[java]
package cn.testcrash;
import android.app.Application;

public class CrashApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        CrashHandler crashHandler=CrashHandler.getInstance();
        //指定Crash时的处理程序
        crashHandler.setCrashHandler(getApplicationContext());
    }
}

package cn.testcrash;
import android.app.Application;

public class CrashApplication extends Application {
@Override
public void onCreate() {
  super.onCreate();
  CrashHandler crashHandler=CrashHandler.getInstance();
  //指定Crash时的处理程序
  crashHandler.setCrashHandler(getApplicationContext());
}
}

CrashHandler如下:

[java]
package cn.testcrash;
import java.lang.Thread.UncaughtExceptionHandler;
import android.content.Context;
import android.os.Looper;
import android.widget.Toast;
public class CrashHandler implements UncaughtExceptionHandler {
    private Context mContext;
    private static CrashHandler mCrashHandler=new CrashHandler();

    public static CrashHandler getInstance(){
        return mCrashHandler;
    }

    /**
     * 设置当线程由于未捕获到异常而突然终止的默认处理程序。
     */
    public void setCrashHandler(Context context){
        mContext=context;
        Thread.setDefaultUncaughtExceptionHandler(this);
    }

    /**
     * 当发生Crash时调用该方法
     */
    @Override
    public void uncaughtException(Thread thread, Throwable throwable) {
         //1 保存错误日志到SD卡
         Utils.saveCrashInfoToSDCard(mContext, throwable);
         //2 提示Crash信息
         showCrashTipToast();
         try {
            Thread.sleep(3000);
        } catch (Exception e) {
        }
         //3 退出应用
         System.exit(0);
    }

    private void showCrashTipToast() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                Looper.prepare();
                Toast.makeText(mContext, "I am very sorry", Toast.LENGTH_LONG).show();
                Looper.loop();
            }
        }).start();
    }

}

package cn.testcrash;
import java.lang.Thread.UncaughtExceptionHandler;
import android.content.Context;
import android.os.Looper;
import android.widget.Toast;
public class CrashHandler implements UncaughtExceptionHandler {
private Context mContext;
private static CrashHandler mCrashHandler=new CrashHandler();

public static CrashHandler getInstance(){
return mCrashHandler;
}

/**
* 设置当线程由于未捕获到异常而突然终止的默认处理程序。
*/
public void setCrashHandler(Context context){
