android App級別的bug資訊收集(crash資訊儲存和傳送)

收集app的crash資訊,儲存併發送給伺服器後端。在對於程式中沒有做異常處理的程式。呼叫系統封裝的UncaughtException類進行處理。

第一步,封裝handler。

第二步、
package com.yisa.qiqilogin.util;

import java.util.ArrayList;
import java.util.List;

import com.yisa.qiqilogin.Handler.CrashHandler;

import android.app.Activity;
import android.app.Application;

/**
 * @ClassName: MyApplication
 * @Description: 獲取context,在androidmanifest.xml檔案中application標籤<android:name="com.yisa.qiqilogin.util.MyApplication"
 * @author 
 * @date 2014-4-9 
 *
 */
public class MyApplication extends Application {
    private static MyApplication instance;
    
    public static MyApplication getInstance() {
    	 if (instance == null) {  
             instance = new MyApplication();  
         }  
         return instance; 
    }

    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
        CrashHandler.getInstance().init(getApplicationContext());  
    }
    
}


第三步、

在manifest檔案中,application標籤下新增android:name="com.yisa.qiqilogin.util.MyApplication"

PS、有可能你的程式已經定義過這種全域性的變數,那麼只要在你已經定義的oncreate方法中初始化一下handler
