Check this out to get adb log:

		String filter = "adb logcat -d <filterName>:V *:S";
		Process p = Runtime.getRuntime().exec(
				(<ADB_Path>).concat(filter));

After this save it to file and validate through java code whether particular tags are present or not

If you are after logcat, appium gives you a mechanism for grabbing them. It’s not very flexible; we just grab all of them. Here’s an example in Ruby. I’ll have to hope you get the general idea and can translate it into Java

appium_driver.driver.manage.logs.get(“logcat”)

  @Test
	public void launchAVD() throws InterruptedException, IOException {
		ProcessBuilder pbEmulator = new ProcessBuilder("emulator", "-avd", "EmulatorAndroidName");
		Process pcEmulator = pbEmulator.start();
		pcEmulator.waitFor();
		
		ProcessBuilder pbADB = new ProcessBuilder("adb", "devices");
		Process pcADB = pbADB.start();
		pcADB.waitFor();
		
		InputStream is = pcADB.getInputStream();
		InputStreamReader isr = new InputStreamReader(is);
		BufferedReader br = new BufferedReader(isr);
		String line;
		String adb = new String();
		
		while ((line = br.readLine()) != null) {
		    if (line.length()>0)
			line += br.readLine();
		    System.out.println(line);
		}
	
		if (adb.contains("emulator-5554") && (!adb.contains("offline"))) {
			System.out.println("Device is connected");	
		}
	}
