MainActivity如下:

package cn.testcrash;
import android.app.Activity;
import android.os.Bundle;
/*** Demo描述:* 借助于Application自定义Crash* * 参考资料:* 1 http://blog.csdn.net/xiaanming/article/details/9344703* 2 http://blog.csdn.net/itachi85/article/details/9102021*/
public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);init();}//Crashprivate void init(){System.out.println((9727/0)+"");}
}

CrashApplication如下:

package cn.testcrash;
import android.app.Application;public class CrashApplication extends Application {@Overridepublic void onCreate() {super.onCreate();CrashHandler crashHandler=CrashHandler.getInstance();//指定Crash时的处理程序crashHandler.setCrashHandler(getApplicationContext());}
}

CrashHandler如下:

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*/@Overridepublic void uncaughtException(Thread thread, Throwable throwable) {//保存错误日志到SD卡Utils.saveInfoToSDCard(mContext, throwable);//提示Crash信息showCrashTipToast();try {Thread.sleep(3000);} catch (Exception e) {}//退出应用System.exit(0);}private void showCrashTipToast() {new Thread(new Runnable() {@Overridepublic void run() {Looper.prepare();Toast.makeText(mContext, "I am very sorry", Toast.LENGTH_LONG).show();Looper.loop();}}).start();}}

Utils如下:

package cn.testcrash;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import java.util.TimeZone;
import android.content.Context;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.os.Build;public class Utils {public static void saveInfoToSDCard(Context context, Throwable throwable) {HashMap<String, String> hashMap=getBaseInfo(context);StringBuilder stringBuilder=new StringBuilder();for(Map.Entry<String, String> entry:hashMap.entrySet()){String key=entry.getKey();String value=entry.getValue();stringBuilder.append(key).append("=").append(value).append("\n");}System.out.println("stringBuilder.toString()如下:"+"\n"+stringBuilder.toString());/*** 其余逻辑省略*/}/*** 获取设备及该App的基本信息*/public static HashMap<String, String> getBaseInfo(Context context){HashMap<String, String> hashMap = new HashMap<String, String>();PackageManager packageManager = context.getPackageManager();PackageInfo packageInfo = null;try {packageInfo = packageManager.getPackageInfo(context.getPackageName(), PackageManager.GET_ACTIVITIES);} catch (NameNotFoundException e) {e.printStackTrace();}hashMap.put("versionName", packageInfo.versionName);hashMap.put("versionCode", packageInfo.versionCode+"");hashMap.put("MODEL",  Build.MODEL+"");hashMap.put("SDK_INT",Build.VERSION.SDK_INT+"");hashMap.put("RELEASE",Build.VERSION.RELEASE+"");hashMap.put("PRODUCT",Build.PRODUCT+"");return hashMap;}private String getCurrentTime(){String currentTime="";long currentTimeMillis=System.currentTimeMillis();System.setProperty("user.timezone", "Asia/Shanghai");  TimeZone timeZone = TimeZone.getTimeZone("Asia/Shanghai");  TimeZone.setDefault(timeZone);  SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");Date currentDate=new Date(currentTimeMillis);currentTime = simpleDateFormat.format(currentDate);  System.out.println("currentTime="+currentTime);return currentTime;}}
