String shell = "logcat"; try { Process process = Runtime.getRuntime().exec(shell); InputStream inputStream = process.getInputStream(); boolean sdCardExist = Environment.getExternalStorageState().equals( android.os.Environment.MEDIA_MOUNTED); File dir = null; if (sdCardExist) { dir = new File(Environment.getExternalStorageDirectory().toString() + File.separator + "logcatwyx.txt"); if (!dir.exists()) { dir.createNewFile(); } } byte[] buffer = new byte[1024]; int bytesLeft = 5 * 1024 * 1024; // Or whatever try { FileOutputStream fos = new FileOutputStream(dir); try { while (bytesLeft > 0) { int read = inputStream.read(buffer, 0, Math.min(bytesLeft, buffer.length)); if (read == -1) { throw new EOFException("Unexpected end of data"); } fos.write(buffer, 0, read); bytesLeft -= read; } } finally { fos.close(); // Or use Guava's // Closeables.closeQuietly, // or try-with-resources in Java 7 } } finally { inputStream.close(); }// String logcat = convertStreamToString(inputStream);// outputFile2SdTest(logcat, "logwyx.txt"); Log.v(TAG, "LOGCAT = ok" ); } catch (IOException e) { e.printStackTrace(); }
pid=`ps | grep logcat | awk '{print $2}'` && kill $pid pid=`ps | grep logcat | awk '{print $2}'` && kill $pid
