 } 

 private static boolean checkRootMethod1() { 

 String buildTags = android.os.Build.TAGS; 

 return buildTags != null && buildTags.contains("test-keys"); 

 } 

 private static boolean checkRootMethod2() {

 String[] paths = { 

"/system/app/Superuser.apk", "/sbin/su", "/system/bin/su", "/system/xbin/su", "/data/local/xbin/su", "/data/local/bin/su", "/system/sd/xbin/su", "/system/bin/failsafe/su", "/data/local/su", "/su/bin/su"

}; 

 for (String path : paths) { 

 if (new File(path).exists()) 

return true;

 } 

 return false; 

 } 

 private static boolean checkRootMethod3() { 

 Process process = null; try {

 process = Runtime.getRuntime().exec(new String[] {

 "/system/xbin/which", "su" 

}); 

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

 if (in.readLine() != null) return true;

 return false; 

 } 

catch (Throwable t) {

 return false; 

 } finally { 

 if (process != null) process.destroy();

 } 

 }
