android崩溃收集

Android崩溃收集可以通过以下步骤实现：

1. 在AndroidManifest.xml文件中添加以下权限：

<uses-permission android:name="android.permission.READ_LOGS"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

2. 在Application类中初始化崩溃捕获工具：

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        CrashHandler.getInstance().init(this);
    }
}

3. 编写一个崩溃捕获工具类CrashHandler：

public class CrashHandler implements Thread.UncaughtExceptionHandler {

    private static CrashHandler instance = new CrashHandler();
    private Thread.UncaughtExceptionHandler defaultHandler;
    private Context context;

    private CrashHandler() {

    }

    public static CrashHandler getInstance() {
        return instance;
    }

    public void init(Context context) {
        this.context = context;
        defaultHandler = Thread.getDefaultUncaughtExceptionHandler();
        Thread.setDefaultUncaughtExceptionHandler(this);
    }

    @Override
    public void uncaughtException(Thread t, Throwable e) {
        if (!handleException(e) && defaultHandler != null) {
            defaultHandler.uncaughtException(t, e);
        } else {
            try {
                Thread.sleep(3000);
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
            android.os.Process.killProcess(android.os.Process.myPid());
            System.exit(1);
        }
    }

    private boolean handleException(Throwable e) {
        if (e == null) {
            return false;
        }
        StringWriter sw = new StringWriter();
        PrintWriter pw = new PrintWriter(sw);
        e.printStackTrace(pw);
        String log = sw.toString();
        Log.e("CrashHandler", log);
        saveLogToFile(log);
        return true;
    }

    private void saveLogToFile(String log) {
        String fileName = "crash-" + System.currentTimeMillis() + ".log";
        try {
            File file = new File(Environment.getExternalStorageDirectory(), fileName);
            FileOutputStream fos = new FileOutputStream(file);
            fos.write(log.getBytes());
            fos.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

4. 在崩溃捕获工具类中，将崩溃信息输出到Logcat和文件中，方便查找和分析。

5. 最后，在应用程序崩溃时，CrashHandler将捕获异常并将其保存到文件中。可以通过查看这些文件来分析崩溃原因并进行修复。
