ACRA 框架的使用 -- 发送到后台解析（后台的代码也在）
使用的工具：Android studio
首先，需要了解的是：
ACRA有3种方式将错误信息提交到后台：
1.邮件形式，但经过测试，发现会调用系统的邮箱进行发送到指定的邮箱，如果没有邮箱，则会报错，如果没有登陆，则要登陆才去发送，很显然，中国很少会登录邮箱的，也懒得登录去发送。第一种方式，不推荐使用。
2.以GoogleDoc形式发送到一个我也不知道怎么搭建的后台。有兴趣的可以去尝试：http://www.jianshu.com/p/fd4d6a7c6175
3.自定义发送器进行发送
这里用的是第3种方式进行提交：
第一步：
配置Gradle：
compile ‘ch.acra:acra:4.9.0‘ // 应用崩溃信息
第二步：
自定义两个类：CrashSenderFactory和CrashSender类，其中发送的内容是在CrashSender中..
package com.lanhetech.testdemo;import android.content.Context;import android.support.annotation.NonNull;import com.orhanobut.logger.Logger;import com.zhy.http.okhttp.OkHttpUtils;import com.zhy.http.okhttp.callback.Callback;import org.acra.ReportField;import org.acra.collector.CrashReportData;import org.acra.sender.ReportSender;import org.acra.sender.ReportSenderException;import okhttp3.Call;import okhttp3.Response;public class CrashSender implements ReportSender { @Override public void send(@NonNull Context context, @NonNull CrashReportData errorContent) throws ReportSenderException { // 自定义需要发送的内容到后台 OkHttpUtils.get() .url("http://h-bolin.imwork.net:14572/TestServlet/servlet/UploadServlet") .addParams("APP_VERSION_CODE", errorContent.getProperty(ReportField.APP_VERSION_CODE)) .addParams("APP_VERSION_NAME", errorContent.getProperty(ReportField.APP_VERSION_NAME)) .addParams("PACKAGE_NAME", errorContent.getProperty(ReportField.PACKAGE_NAME)) .addParams("FILE_PATH", errorContent.getProperty(ReportField.FILE_PATH)) .addParams("PHONE_MODEL", errorContent.getProperty(ReportField.PHONE_MODEL)) .addParams("ANDROID_VERSION", errorContent.getProperty(ReportField.ANDROID_VERSION)) .addParams("BUILD", errorContent.getProperty(ReportField.BUILD)) .addParams("BRAND", errorContent.getProperty(ReportField.BRAND)) .addParams("STACK_TRACE", errorContent.getProperty(ReportField.STACK_TRACE)) .addParams("STACK_TRACE_HASH", errorContent.getProperty(ReportField.STACK_TRACE_HASH)) .addParams("USER_CRASH_DATE", errorContent.getProperty(ReportField.USER_CRASH_DATE)) .addParams("DUMPSYS_MEMINFO", errorContent.getProperty(ReportField.DUMPSYS_MEMINFO)) .addParams("DEVICE_ID", errorContent.getProperty(ReportField.DEVICE_ID)) .build() .execute(new Callback() { @Override public Object parseNetworkResponse(Response response, int id) throws Exception { Logger.d("response=" + response.toString()); return null; } @Override public void one rror(Call call, Exception e, int id) { } @Override public void onResponse(Object response, int id) { } }); }}
package com.lanhetech.testdemo;import android.content.Context;import android.support.annotation.NonNull;import org.acra.config.ACRAConfiguration;import org.acra.sender.ReportSender;import org.acra.sender.ReportSenderFactory;public class CrashSenderFactory implements ReportSenderFactory { @NonNull @Override public ReportSender create(@NonNull Context context, @NonNull ACRAConfiguration config) { return new CrashSender(); }}
第三步：
自定义MyApplication
package com.lanhetech.testdemo;import android.app.Application;import android.content.Context;import org.acra.ACRA;import org.acra.ReportingInteractionMode;import org.acra.annotation.ReportsCrashes;@ReportsCrashes( mode = ReportingInteractionMode.TOAST, resToastText = R.string.app_error, // 更换默认的发送器 reportSenderFactoryClasses = {com.lanhetech.testdemo.CrashSenderFactory.class})public class MyApplication extends Application { @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); ACRA.init(this); } @Override public void onCreate() { super.onCreate(); }}
第四步：
修改AndroidManifest.xml内容，获取权限
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.lanhetech.testdemo"> <!--获取权限--> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> <!--修改这里application name--> <application android:name=".MyApplication" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".Main2Activity"></activity> </application></manifest>
到这里，ARCA就配置好了，但需要后台的配合。
以下是web的Servlet的代码：
@Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // TODO Auto-generated method stub // super.doGet(req, resp); System.out.println("参数内容：" + req.getParameter("APP_VERSION_CODE")); System.out.println("参数内容：" + req.getParameter("APP_VERSION_NAME")); System.out.println("参数内容：" + req.getParameter("PACKAGE_NAME")); System.out.println("参数内容：" + req.getParameter("FILE_PATH")); System.out.println("参数内容：" + req.getParameter("PHONE_MODEL")); System.out.println("参数内容：" + req.getParameter("ANDROID_VERSION")); System.out.println("参数内容：" + req.getParameter("BUILD")); System.out.println("参数内容：" + req.getParameter("BRAND")); System.out.println("参数内容：" + req.getParameter("STACK_TRACE")); System.out.println("参数内容：" + req.getParameter("STACK_TRACE_HASH")); System.out.println("参数内容：" + req.getParameter("USER_CRASH_DATE")); System.out.println("参数内容：" + req.getParameter("DUMPSYS_MEMINFO")); System.out.println("参数内容：" + req.getParameter("DEVICE_ID")); PrintWriter out = resp.getWriter(); out.println("0"); out.flush(); out.close(); }
测试:
public class MainActivity extends AppCompatActivity { private ImageView main_show_img; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); "1".substring(5); }}

注意点：
首先需要注意一点,Acra使用独立进程:acra,进行采集数据的发送，保证当app崩溃时，采集仍然能发送出去。
由于使用独立的进程，所以会导致application被实例化多次，这样就需要注意app自身的某些业务逻辑，不要在application类中执行多次，从而导致app产生bug。
对Acra的相关配置一般在application中进行初始化。
