全局异常捕获-使用的是腾讯的Bugly

1.配置ndk

android {
defaultConfig {
ndk {
// 设置支持的SO库架构
abiFilters 'armeabi' //, 'x86', 'armeabi-v7a', 'x86_64', 'arm64-v8a'
}
}
}

2.添加依赖

dependencies {
compile 'com.tencent.bugly:crashreport:latest.release' //其中latest.release指代最新Bugly SDK版本号，也可以指定明确的版本号，例如2.1.9
compile 'com.tencent.bugly:nativecrashreport:latest.release' //其中latest.release指代最新Bugly NDK版本号，也可以指定明确的版本号，例如3.0
}

3.导入CrashHandler类

public class CrashHandler implements Thread.UncaughtExceptionHandler {

private static CrashHandler sInstance = null;
private Thread.UncaughtExceptionHandler mDefaultHandler;
private Context mContext;
// 保存手机信息和异常信息
private Map<String, String> mMessage = new HashMap<>();

public static CrashHandler getInstance() {
if (sInstance == null) {
synchronized (CrashHandler.class) {
if (sInstance == null) {
synchronized (CrashHandler.class) {
sInstance = new CrashHandler();
}
}
}
}
return sInstance;
}

private CrashHandler() {
}

/**
* 初始化默认异常捕获
*
* @param context context
*/
public void init(Context context) {
mContext = context;
// 获取默认异常处理器
mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();
// 将此类设为默认异常处理器
Thread.setDefaultUncaughtExceptionHandler(this);
}

@Override
public void uncaughtException(Thread t, Throwable e) {
if (!handleException(e)) {
// 未经过人为处理,则调用系统默认处理异常,弹出系统强制关闭的对话框
if (mDefaultHandler != null) {
mDefaultHandler.uncaughtException(t, e);
}
} else {
// 已经人为处理,系统自己退出
try {
Thread.sleep(1000);
} catch (InterruptedException e1) {
e1.printStackTrace();
}
System.exit(1);
}
}

/**
* 是否人为捕获异常
*
* @param e Throwable
* @return true:已处理 false:未处理
*/
private boolean handleException(Throwable e) {
if (e == null) {// 异常是否为空
return false;
}
new Thread() {// 在主线程中弹出提示
@Override
public void run() {
Looper.prepare();
Toast.makeText(mContext, "捕获到异常", Toast.LENGTH_SHORT).show();
Looper.loop();
}
}.start();
collectErrorMessages();
saveErrorMessages(e);
return false;
}

/**
* 1.收集错误信息
*/
private void collectErrorMessages() {
PackageManager pm = mContext.getPackageManager();
try {
PackageInfo pi = pm.getPackageInfo(mContext.getPackageName(), PackageManager.GET_ACTIVITIES);
if (pi != null) {
String versionName = TextUtils.isEmpty(pi.versionName) ? "null" : pi.versionName;
String versionCode = "" + pi.versionCode;
mMessage.put("versionName", versionName);
mMessage.put("versionCode", versionCode);
}
// 通过反射拿到错误信息
Field[] fields = Build.class.getFields();
if (fields != null && fields.length > 0) {
for (Field field : fields) {
field.setAccessible(true);
try {
mMessage.put(field.getName(), field.get(null).toString());
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}

/**
* 2.保存错误信息
*
* @param e Throwable
*/
private void saveErrorMessages(Throwable e) {
StringBuilder sb = new StringBuilder();
for (Map.Entry<String, String> entry : mMessage.entrySet()) {
String key = entry.getKey();
String value = entry.getValue();
sb.append(key).append("=").append(value).append("\n");
}
Writer writer = new StringWriter();
PrintWriter pw = new PrintWriter(writer);
e.printStackTrace(pw);
pw.close();
String result = writer.toString();
sb.append(result);
// String time = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss",Locale.CHINA).format(new Date());
String fileName = "crash-"+System.currentTimeMillis()+"-"+".log";
// 有无SD卡
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
String path = Environment.getExternalStorageDirectory().getPath()+"/crash/";
File dir = new File(path);
if (!dir.exists()) dir.mkdirs();
FileOutputStream fos = null;
try {
fos = new FileOutputStream(path + fileName);
fos.write(sb.toString().getBytes());
} catch (Exception e1) {
e1.printStackTrace();
} finally {
if (fos != null) {
try {
fos.close();
} catch (IOException e1) {
e1.printStackTrace();
}
}
}
}
}
}

4.创建一个application类

CrashHandler.getInstance().init(this);
CrashReport.initCrashReport(getApplicationContext(), "注册时申请的APPID", false);

5.加权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_LOGS" />
