Read logcat programmatically for an application

问题

I've read this article already. But it seems most of the text it shows are not in my application. How can I filter the message and let it only shows the log for my application. In another word, I want to show it like the one in Android Studio (only showing the error log from my app, showing time stamp,etc):

I tried something like "logcat -d -v time", but doesn't work. Any idea? Thanks.

Try following code to get logs of your application only.

public final class MyAppLogReader {

    private static final String TAG = MyAppLogReader.class.getCanonicalName();
    private static final String processId = Integer.toString(android.os.Process
            .myPid());

    public static StringBuilder getLog() {

        StringBuilder builder = new StringBuilder();

        try {
            String[] command = new String[] { "logcat", "-d", "-v", "threadtime" };

            Process process = Runtime.getRuntime().exec(command);

            BufferedReader bufferedReader = new BufferedReader(
                    new InputStreamReader(process.getInputStream()));

            String line;
            while ((line = bufferedReader.readLine()) != null) {
                if (line.contains(processId)) {
                    builder.append(line);
                    //Code here
                }
            }
        } catch (IOException ex) {
            Log.e(TAG, "getLog failed", ex);
        }

        return builder;
    }
}

Edit

Add below permission to your AndroidManifest file

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