android App級別的bug資訊收集(crash資訊儲存和傳送)
阿新 • • 發佈:2019-02-16
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.Handler; import java.io.PrintWriter; import java.io.StringWriter; import java.io.Writer; import java.lang.Thread.UncaughtExceptionHandler; import java.lang.reflect.Field; import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.ArrayList; import java.util.Date; import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import org.apache.http.NameValuePair; import org.apache.http.message.BasicNameValuePair; import org.json.JSONArray; import org.json.JSONObject; import android.content.Context; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.content.pm.PackageManager.NameNotFoundException; import android.os.AsyncTask; import android.os.Build; import android.os.Environment; import android.os.Looper; import android.util.Log; import android.widget.Toast; import com.yisa.qiqilogin.R; import com.yisa.qiqilogin.util.HttpClientUtil; import com.yisa.qiqilogin.util.MyApplication; /** * @ClassName: CrashHandler * @Description UncaughtException處理類,當程式發生Uncaught異常的時候,有該類來接管程式,並記錄傳送錯誤報告. * 需要在Application中註冊,為了要在程式啟動器就監控整個程式。 * @author hq * @date 2015年1月20日 下午4:58:57 * */ public class CrashHandler implements UncaughtExceptionHandler { public static final String TAG = "CrashHandler"; //系統預設的UncaughtException處理類 private Thread.UncaughtExceptionHandler mDefaultHandler; //CrashHandler例項 private static CrashHandler instance; //程式的Context物件 private Context mContext; //用來儲存裝置資訊和異常資訊 private Map<String, String> infos = new HashMap<String, String>(); //用於格式化日期,作為日誌檔名的一部分 private DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss"); //自定義執行緒池 private static ExecutorService FULL_TASK_EXECUTOR; //要傳送的伺服器地址 private static String ServerAddress = "http://192.168.1.110:8080/YiSaPushServer/collections.jsp"; static { FULL_TASK_EXECUTOR = (ExecutorService) Executors.newCachedThreadPool(); }; /** 保證只有一個CrashHandler例項 */ private CrashHandler() { } /** 獲取CrashHandler例項 ,單例模式 */ public static CrashHandler getInstance() { if (instance == null) instance = new CrashHandler(); return instance; } /** * 初始化 */ public void init(Context context) { mContext = context; //獲取系統預設的UncaughtException處理器 mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler(); //設定該CrashHandler為程式的預設處理器 Thread.setDefaultUncaughtExceptionHandler(this); } /** * 當UncaughtException發生時會轉入該函式來處理 */ @Override public void uncaughtException(Thread thread, Throwable ex) { if (!handleException(ex) && mDefaultHandler != null) { //如果使用者沒有處理則讓系統預設的異常處理器來處理 mDefaultHandler.uncaughtException(thread, ex); } else { try { Thread.sleep(3000); } catch (InterruptedException e) { Log.e(TAG, "error : ", e); } //退出程式 android.os.Process.killProcess(android.os.Process.myPid()); System.exit(1); } } /** * 自定義錯誤處理,收集錯誤資訊 傳送錯誤報告等操作均在此完成. * @param ex * @return true:如果處理了該異常資訊;否則返回false. */ private boolean handleException(Throwable ex) { if (ex == null) { return false; } //收集裝置引數資訊 collectDeviceInfo(mContext); //使用Toast來顯示異常資訊 new Thread() { @Override public void run() { Looper.prepare(); Toast.makeText(mContext, "很抱歉,程式出現異常,即將退出.", Toast.LENGTH_SHORT).show(); Looper.loop(); } }.start(); //儲存日誌檔案 saveCatchInfo2File(ex); return true; } /** * 收集裝置引數資訊 * @param ctx */ public void collectDeviceInfo(Context ctx) { try { PackageManager pm = ctx.getPackageManager(); PackageInfo pi = pm.getPackageInfo(ctx.getPackageName(), PackageManager.GET_ACTIVITIES); if (pi != null) { String versionName = pi.versionName == null ?

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
