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:
* http://blog.csdn.net/lfdfhl/article/details/9261147
* http://blog.csdn.net/lfdfhl/article/details/9260605

* Thank you very much

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)+"");
}
}

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){
