[Q]scan for ble device

I'm trying to develop an app to scan for a BLE device. However, it only scans one time. I tried to use a while loop to loop it but it hangs there. The scanning part is at the proceed function:
Code:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hello();
}
public void hello() {
if (mBluetoothAdapter == null || !mBluetoothAdapter.isEnabled()) {
Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBluetooth, 1);
}
proceed();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if (resultCode == RESULT_OK) {
proceed();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() {
public void onLeScan(final BluetoothDevice device, final int rssi, final byte[] scanRecord) {
int startByte = 2;
boolean patternFound = false;
while (startByte <= 5) {
if (((int) scanRecord[startByte + 2] & 0xff) == 0x02 && //Identifies an iBeacon
((int) scanRecord[startByte + 3] & 0xff) == 0x15) { //Identifies correct data length
patternFound = true;
break;
}
startByte++;
}
if (patternFound) {
//Convert to hex String
byte[] uuidBytes = new byte[16];
System.arraycopy(scanRecord, startByte + 4, uuidBytes, 0, 16);
String hexString = bytesToHex(uuidBytes);
//Here is your UUID
String uuid = hexString.substring(0, 8) + "-" +

//Here is your Minor value
int minor = (scanRecord[startByte + 22] & 0xff) * 0x100 + (scanRecord[startByte + 23] & 0xff);
if (major == 1) {
RelativeLayout hai = (RelativeLayout) findViewById(R.id.hai);
hai.setBackgroundColor(Color.YELLOW);
}
if (major == 2) {
RelativeLayout hai = (RelativeLayout) findViewById(R.id.hai);
hai.setBackgroundColor(Color.RED);
}
}
}
};
private static String bytesToHex(byte[] bytes) {
final char[] hexArray = "0123456789ABCDEF".toCharArray();
char[] hexChars = new char[bytes.length * 2];
for (int j = 0; j < bytes.length; j++) {
int v = bytes[j] & 0xFF;
hexChars[j * 2] = hexArray[v >>> 4];
hexChars[j * 2 + 1] = hexArray[v & 0x0F];
}
return new String(hexChars);
}
public void proceed() {
boolean scanning = true;

ArrayList IndexOutOfBound Error

Hi! I am currently doing on a project and I keep hitting the same error despite making changes. I have been hitting indexOutOfBound error and unable to delete my listView item because of that error. I am doing on Tab and Database. Can anyone help me with my error and problem? Thank you!!

Can help me to see what's wrong? Thank you !!!!

I can't read the all code, it's too long, but ai think that you want to access for example array [5], but array length is smaller.

Need help deleting childview from groupview in expandablelistview w/custom adapter

Hey guys, I am having problem with deleting the childview from my expandablelistview. It deletes (I think), however, when I add a new childview, it is the exact same as the one I just deleted.
youtu.be/eJjR9FEpaaY
codes below

My activity
Code:
public class PlanSetterAct extends AppCompatActivity {
private Button nextBtn;
private EditText planName, weekNum;
private ExpandableListView weekdayList;
List<String> listDataHeader;
HashMap<String, List<String>> listDataChild;
private PlanSetterListAdapter adapter;

weekNum = (EditText) findViewById(R.id.plan_num_edit);
prepareNextButton();
prepareExerciseList();

how to change/replace class constants

i have a class like this
PHP:
package com.insight.sdk;
public class ISBuildConfig {
public static int ASSETS_JAR_VERSION_CODE = 100043;
public static String ASSETS_JAR_VERSION_NAME = "v100.1.2.0_release";
public static boolean DEBUG = false;
public static int LOADER_VERSION_CODE = 100043;
public static String LOADER_VERSION_NAME = "v2.1.3_release";
public static final int NOUGAT = 24;
}
i want to change DEBUG to true
how to use xposed to change this value?

how to use xposed to change this value?
Click to expand...
Click to collapse
Try kooking it as early as possible (Application's onCreate() is a good place to do that):
PHP:
XposedHelpers.findAndHookMethod(>>> APPLICATION.class <<<, "onCreate", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
XposedHelpers.setStaticBooleanField(ISBuildConfig.class, "DEBUG", true);
}
}
