android開發異常資訊收集程式程式碼
阿新 • • 發佈：2019-01-02
首先建立全域性的Application ，此Application全域性通用。
package com.demo.utils; import com.demo.exception.CrashHandler; import android.app.Application; /** * 全域性的context,任意位置呼叫 * @author Administrator * */ public class GlobalApplication extends Application { private static GlobalApplication instance; public static GlobalApplication getInstance() { return instance; } @Override public void onCreate() { super.onCreate(); instance = this; CrashHandler crashHandler = CrashHandler.getInstance();//這是收集異常資訊的單例類，具體程式碼請看下文 crashHandler.init(getApplicationContext());//初始化 } }
注意：上面的程式碼需要在註冊清單檔案中註冊。部分清單如下:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.demo.test" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="18" /> <!-- 網路 --> <uses-permission android:name="android.permission.INTERNET" /> <!-- 訪問sdcard --> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <!-- 獲取mac需要的網路狀態 --> <uses-permission android:name="andorid.permission.CHANGE_CONFIGURATION" /> <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <application android:name="com.demo.utils.GlobalApplication" android:allowBackup="true" android:icon="@drawable/app_icon" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.demo.activity.MyActivity" android:launchMode="singleTask" android:screenOrientation="landscape" android:theme="@android:style/Theme.NoTitleBar" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </activity> </application> </manifest>
crashHandler
