[Q] How to use Timer to restart record video for every preset interval time?

Can someone tell me how can i use something like a timer to start a video recording interval process for a period of time (eg: 5mins) then restarts to record another set of 5min video until the user intervene to stop the process..
Code:
public class ServiceRecording extends Service {
@Override
public IBinder onBind(Intent intent) {

super.onStartCommand(intent, flags, startId);
if (recordingStatus == false)
startRecording();
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
stopRecording();
//camera.stopPreview();

someone please help...

Thread
you are writing a service, right? typically this service should also implement a thread. inside this thread you could implement your timer feature.
-didi

But the thing is i don't know how to even implement or even write the timer codes into my serviceRecording.java file... Can you help me on this?

i recently did this with a widget. i used an AlarmManager to set repeating alarms that would broadcast an intent that could be caught by a broadcastReciever and then do something... im at work now but when i get home i can try to give you some sample code.

you sure this needs to be a service? a service is something that is doing work but not at the forefront of the ui. its unseen. do you want your recording to be done in the background? i only ask because i did some research on services and found that they cannot be a BroadCastReciever and thus cannot use the AlarmManager that i said would work.
as far as a timer i have not looked into that particular class...
sorry i was no help. but if you decide to use the AlarmManager i could help

Someone recently recommended using these code to implement the sort of interval recording i wanted with this code below but i don't seems to know how to implement these codes into my current code could someone lend me a hand how how can can i implement the appropriate codes into my code to make my code work? Or is there simpler way to achieve "dynamic" (with Preferences) interval recording?
Code:
final ServiceRecording recording = ....
final AtomicBoolean started = new AtomicBoolean(false);
ScheduledExecutorService executor = Executors.newScheduledExecutor(1);
executor.scheduleAtFixedRate(new Runnable() { public void run() { //only stop if we have started if(started.get()) { recording.stop(); } else { started.set(true); } recording.start(); }}, 5, 5, TimeUnit.MINUTES);

Any progress on this? I was thinking you coukd have a private inner class in your service class that handles the timing with an AlarmManager
Im on my phone right now but something along these lines...
Private Class MyTimer extends BroadcastReciever {
//Implement onRecieve
Public void onRecieve(Context c, Intent i) {
//if intent matches 5min alarm
//start recording
}
Then in your service you can make a recurring alarm using the AlarmManager class to signal your inner class to start or even stop the recording based on what intent you pass it
When i get home ill right a bit more code as an example
From something awesome

i wrote a bit of code. its incomplete. and you will have to maybe mess with making the AlarmServicer class either static, public, private or something to make it work. basicly your service creates a five minute alarm directed at the AlarmServicer that it catches in the onRecieve() method and then starts your recording again and then creates another alarm directed at itself. you can use some if/then logic to change wether or not the alarm will be created again based on if the user wants it to stop or not. and then to get it going again the service would invoke the setOneTimeAlarm method again.
Code:
public class ServiceRecording extends Service {
// NEW CONSTANT
public static final String FIVE_MIN_ALARM = "FIVE_MIN_ALARM";
public static final int FIVE_MINUTES = 300;
@Override
public void onCreate() {
super.onCreate();
recordingStatus = false;
ServiceCamera = CameraTest.MainCamera;
surfaceView = CameraTest.surfaceView;
surfaceHolder = CameraTest.surfaceHolder;
//set the first alarm
AlarmServicer.setOneTimeAlarm(AlarmServicer.class, this, ServiceRecording.FIVE_MINUTES , ServiceRecording.FIVE_MIN_ALARM);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) { }
public boolean startRecording() {}
public void stopRecording() {}
// NEW CODE
private static class AlarmServicer extends BroadcastReciever {
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (intent.getAction().equals(ServiceRecording.FIVE_MIN_ALARM)) {
ServiceRecording.startRecording();
//set another five min alarm
setOneTimeAlarm(AlarmServicer.class, this, ServiceRecording.FIVE_MINUTES, ServiceRecording.FIVE_MIN_ALARM;
}
}
private static void setOneTimeAlarm(java.lang.Class<?> cls, Context context, int seconds, String action) {
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, cls);
intent.setAction(action);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (seconds * 1000), pendingIntent);
}
}
}
and i believe that you need to register the inner class as a broadcastreciever in the android manifest.

Have you declared an edittext in a layout? maybe you need to change the id of this line.
EditText editText = (EditText) findViewById(R.id.edit_message);, or maybe connection parameters are wrong...or you miss something...post the logcat!

FC when using interface to launch new fragment form listView

I have an async task that loads a list view of items. I am currently trying to set the onClick to load a new fragment with an "id" that is being retrieved from the list item that is clicked. I have no errors in my code that the Android Studio shows me.
When I run the app and click on the item in the list view I get this FC:

Let me know if you need any other code, I am stomped on this and could use a second pair of eyes. Thanks.

Android getting SMS body from inbox

Hi,
I want to get body of SMS when I click on one. I have tried an approach simmilar to contact picker. Here is my code :
public class Decrypt extends Fragment {
Button loadButton;
EditText smsDisplay;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.decrypt, null);
// Button loadButton=(Button)v.findViewById(R.id.)
loadButton=(Button)v.findViewById(R.id.buttonLoad);
smsDisplay=(EditText)v.findViewById(R.id.editTextLoad);
loadButton.setOnClickListener(new OnClickListener() {
@override
public void onClick(View v) {
Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.setData(Uri.parse("sms:"));
//sendIntent.setType(Sm)
//sendIntent.putExtra("sms_body","");
startActivityForResult(sendIntent,2);
}
});
return v;
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
try{
// if (resultCode == Activity.RESULT_OK) {
Uri ur = data.getData();
Cursor c = getActivity().getContentResolver().query(ur, null, null, null, null);
if (c.moveToFirst()) {
String s = c.getString(c.getColumnIndex("body"));
System.out.println(s);
Toast.makeText(getActivity(), s, Toast.LENGTH_LONG).show();
smsDisplay.setText(s);
}
}catch(Exception e){
e.printStackTrace();
}
// }
}
}
It opens a Inbox like when I open original sms app in anroid, but when I click on one message it doesnt copy body of that sms in my edittext. Please couul you look at my code and find mistake?
Thanks a lot for your time

BLE Application (Display data from characteristic in a textView)

I used the BluetoothLeGatt example code to write an app that automatically connects to a bonded BLE peripheral upon launching the app. Now i am trying to display the data from one of the peripheral's characteristic in a textView. The BluetoothLeGatt example code only demonstrates this using ExpandableListView.OnChildClickListener, my app should require no user input and simply get he data from the characteristic. This is what i have so far:
Code:
private TextView mConnectionState;
private TextView mDataField;
private String mDeviceName;
private String mDeviceAddress;
private ExpandableListView mGattServicesList;
private BluetoothLeService mBluetoothLeService;
private boolean mConnected = false;
private BluetoothGattCharacteristic mNotifyCharacteristic;
private final String LIST_NAME = "NAME";
private final String LIST_UUID = "UUID";
// Code to manage Service lifecycle.
private final ServiceConnection mServiceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName componentName, IBinder service) {
mBluetoothLeService = ((BluetoothLeService.LocalBinder) service).getService();
if (!mBluetoothLeService.initialize()) {
Log.e(TAG, "Unable to initialize Bluetooth");
finish();
}
// Automatically connects to the device upon successful start-up initialization.
mBluetoothLeService.connect(mDeviceAddress);
}
@Override
public void onServiceDisconnected(ComponentName componentName) {
mBluetoothLeService = null;
}
};
// Handles various events fired by the Service.
// ACTION_GATT_CONNECTED: connected to a GATT server.
// ACTION_GATT_DISCONNECTED: disconnected from a GATT server.
// ACTION_GATT_SERVICES_DISCOVERED: discovered GATT services.
// ACTION_DATA_AVAILABLE: received data from the device. This can be a result of read
// or notification operations.
private final BroadcastReceiver mGattUpdateReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (BluetoothLeService.ACTION_GATT_CONNECTED.equals(action)) {
mConnected = true;
updateConnectionState(R.string.connected);
mConnectionState.setTextColor(Color.parseColor("#FF17AA00"));
invalidateOptionsMenu();
} else if (BluetoothLeService.ACTION_GATT_DISCONNECTED.equals(action)) {
mConnected = false;
updateConnectionState(R.string.disconnected);
invalidateOptionsMenu();
clearUI();
} else if (BluetoothLeService.ACTION_GATT_SERVICES_DISCOVERED.equals(action)) {
*edit*
UUID chara = UUID.fromString("c97433f0-be8f-4dc8-b6f0-5343e6100eb4");
List<BluetoothGattService> servs = mBluetoothLeService.getSupportedGattServices();
for (int i = 0; servs.size() > i; i++) {
List<BluetoothGattCharacteristic> charac = servs.get(i).getCharacteristics();
for (int j = 0; charac.size() > i; i++) {
BluetoothGattCharacteristic ch = charac.get(i);
if (ch.getUuid() == chara) {
mBluetoothLeService.readCharacteristic(ch);
mBluetoothLeService.setCharacteristicNotification(ch, true);
}
}
}
} else if (BluetoothLeService.ACTION_DATA_AVAILABLE.equals(action)) {
displayData(intent.getStringExtra(BluetoothLeService.EXTRA_DATA));
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_device_control);
final Intent intent = getIntent();
mDeviceName = intent.getStringExtra(EXTRAS_DEVICE_NAME);
mDeviceAddress = intent.getStringExtra(EXTRAS_DEVICE_ADDRESS);
mConnectionState = (TextView) findViewById(R.id.connection_state);
mDataField = (TextView) findViewById(R.id.data);
Intent gattServiceIntent = new Intent(this, BluetoothLeService.class);
bindService(gattServiceIntent, mServiceConnection, BIND_AUTO_CREATE);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
@Override
protected void onResume() {
super.onResume();
registerReceiver(mGattUpdateReceiver, makeGattUpdateIntentFilter());
if (mBluetoothLeService != null) {
final boolean result = mBluetoothLeService.connect(mDeviceAddress);
Log.d(TAG, "Connect request result=" + result);
}
}
@Override
protected void onPause() {
super.onPause();
unregisterReceiver(mGattUpdateReceiver);
}
@Override
protected void onDestroy() {
super.onDestroy();
unbindService(mServiceConnection);
mBluetoothLeService = null;
}
private void updateConnectionState(final int resourceId) {
runOnUiThread(new Runnable() {
@Override
public void run() {
mConnectionState.setText(resourceId);
}
});
}
private void displayData(String data) {
if (data != null) {
mDataField.setText(data);
}
}
private void clearUI() {
mGattServicesList.setAdapter((SimpleExpandableListAdapter) null);
mDataField.setText(R.string.no_data);
}
private static IntentFilter makeGattUpdateIntentFilter() {
final IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(BluetoothLeService.ACTION_GATT_CONNECTED);
intentFilter.addAction(BluetoothLeService.ACTION_GATT_DISCONNECTED);
intentFilter.addAction(BluetoothLeService.ACTION_GATT_SERVICES_DISCOVERED);
intentFilter.addAction(BluetoothLeService.ACTION_DATA_AVAILABLE);
return intentFilter;
}
I've successfully connected to an already bonded device, but now im trying to get the data from a characteristic using its uuid and display it in a textView. The BluetoothLeGatt example shows how a characteristic is selected by a user using an expandable list view onclick listener displaying the supported characteristics. I want to bypass all that and just get the data from the characteristic with the known uuid.
-EDIT-
figured it out
