I used this code it's working when i called from activity and fragment
import com.google.android.gms.ads.identifier.AdvertisingIdClient.Info;
Info adInfo = null;
try {
adInfo = AdvertisingIdClient.getAdvertisingIdInfo(mContext);
} catch (IOException e) {
e.printStackTrace();
} catch (GooglePlayServicesAvailabilityException e) {
e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
String AdId = adInfo.getId();
But when i called from pending intent like Package Removed then i want to call the web service at that time i need advertising id but i got null.if you people had done previously please suggest me.thanks in advance.
try use app context
as receivers could use activity context or app context - depends who&how started the receiver
AdvertisingIdClient.getAdvertisingIdInfo(context.getApplicationContext());
You can try this code and call the bellow method on onCreate
public void getAAID()
{
AsyncTask.execute(new Runnable() {
#Override
public void run() {
try {
AdvertisingIdClient.Info adInfo = AdvertisingIdClient.getAdvertisingIdInfo(MyActivity.this);
String myId = adInfo != null ? adInfo.getId() : null;
Log.i("UIDMY",myId);
} catch (Exception e) {
Log.e("error", e);
}
}
});
}

I developing VOIP android application that make and receive the sip call.I Build the pjsip lilbrary as described in "http://trac.pjsip.org/repos/wiki/Getting-Started/Android".
1. Hold
MainActivity.prm.setOptions(pjsua_call_flag.PJSUA_CALL_UPDATE_CONTACT
.swigValue());
try {
MainActivity.currentCall.setHold(MainActivity.prm);
} catch (Exception e) {
e.printStackTrace();
}
I found this code on pjsip documentation,but this code does not work for put a call on Hold.There is no error message return.
2.Unhold
MainActivity.prm = new CallOpParam(true);
MainActivity.prm.getOpt().setFlag(1);
try {
MainActivity.currentCall.reinvite(MainActivity.prm);
} catch (Exception e) {
e.printStackTrace();
}
Thanks.
Here is my code for hold and unHold:
public void setHold(boolean hold) {
if ((localHold && hold) || (!localHold && !hold)) return;
if(currentCall == null) return;
CallOpParam param = new CallOpParam(true);
try {
if (hold) {
currentCall.setHold(param);
localHold = true;
} else {
CallSetting opt = param.getOpt();
opt.setAudioCount(1);
opt.setVideoCount(0);
opt.setFlag(pjsua_call_flag.PJSUA_CALL_UNHOLD.swigValue());
currentCall.reinvite(param);
localHold = false;
}
} catch (Exception e) {}
}
I hope it's helpful.
I'm making an app that needs to connect with a bluetooth device and get data from it... that device is set as master, so I needed to implement a Thread, where I listenUsingRfcommWithServiceRecord and wait for a connection from it:
public AcceptThread(Context context, String serverName, UUID myUUID) {
this.context = context;
BluetoothServerSocket tmp = null;
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
try {
// MY_UUID is the app's UUID string, also used by the client code
tmp = mBluetoothAdapter.listenUsingRfcommWithServiceRecord(serverName, myUUID);
} catch (IOException e) { }
mmServerSocket = tmp;
}
Then on run I run the code socket = mmServerSocket.accept(5000) to wait until it starts pairing with the device:
public void run() {
BluetoothSocket socket = null;
while (true) {
try {
socket = mmServerSocket.accept(5000);
} catch (IOException e) {
Log.e(TAG,"IOException: " + e);
}
// If a connection was accepted
if (socket != null) {
// Manage the connection
ManageConnectedSocket manageConnectedSocket = new ManageConnectedSocket(socket);
manageConnectedSocket.run();
try {
mmServerSocket.close();
} catch (IOException e) {
Log.e(TAG, "IOException: " + e);
}
break;
}
}
}
The Device asks for an authentication PIN, and I need to have an automatic procedure... for that I though of implementing a broadcast receiver to know when the device is asked to par with another device:
IntentFilter filter = new IntentFilter(ACTION_PAIRING_REQUEST);
context.registerReceiver(mPairReceiver, filter);
and receive it:
private final BroadcastReceiver mPairReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (ACTION_PAIRING_REQUEST.equals(action)) {
Log.e(TAG,"ACTION_PAIRING_REQUEST");
setBluetoothPairingPin(device);
}
}
};
In my setBluetoothPairingPin method I receive a BluetoothDevice object :
public void setBluetoothPairingPin(BluetoothDevice device) {
byte[] pinBytes = convertPinToBytes("0000");
try {
Log.e(TAG, "Try to set the PIN");
Method m = device.getClass().getMethod("setPin", byte[].class);
m.invoke(device, pinBytes);
Log.e(TAG, "Success to add the PIN.");
try {
device.getClass().getMethod("setPairingConfirmation", boolean.class).invoke(device, false);
Log.e(TAG, "Success to setPairingConfirmation.");
} catch (Exception e) {
// TODO Auto-generated catch block
Log.e(TAG, e.getMessage());
e.printStackTrace();
}
} catch (Exception e) {
Log.e(TAG, e.getMessage());
e.printStackTrace();
}
}
The problem is that I can't know when my socket receives information, and consecutively, can't know what is my BluetoothDevice to set Pairing Pin before it's connected...
Can someone help me on how to surpass this? Or is there other way to put the pin authentication when I'm listenning from BluetoothServerSocket?
If I'm not explaining correctly, please let me know...
Thanks in advance
With the help from this and this, I was able to make work for me...
My confusion was with the method setBluetoothPairingPin that I couldn't understand that the ACTION_PAIRING_REQUEST is actually called when the device is being starting to pairing, and that is when the PIN is asked from the user... so invoking BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);, and changing a bit of the set pairing method I manage to make it work...
Here's my final code:
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (ACTION_PAIRING_REQUEST.equals(action)) {
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
String PIN = "0000";
byte[] pin = new byte[0];
try {
pin = (byte[]) BluetoothDevice.class.getMethod("convertPinToBytes", String.class).invoke(BluetoothDevice.class, PIN);
BluetoothDevice.class.getMethod("setPin", byte[].class).invoke(device, pin);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
}
}
I've recently migrated from android webview to Crosswalk 13. The only issue i've run into is telling the XWalkView to load content from the app cache.
In my android webview implementation i had implmemented as this
//check connection on a loop
public void CheckConnectivityTask(){
new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... params) {
//runs every 0.5s
try {
Thread.sleep(500);
} catch (InterruptedException e) {
}
return null;
}
#Override
protected void onPostExecute(Void result) {
CheckConnectivity(true);
}
}.execute();
}
public void CheckConnectivity(boolean recursiveTask){
cm = (ConnectivityManager) getSystemService(Activity.CONNECTIVITY_SERVICE);
if(cm != null && cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isConnected()){
Log.v("ConnectivityGG", "IS CONNECTED");
mainWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
}
else{
mainWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}
if(recursiveTask){
CheckConnectivityTask();
}
}
As getSettings() has now been removed from XWalk 13, I've been trying to set this using XWalkSettings
inside OnCreate in MainActivity
xWalkSettings = new XWalkSettings(mainWebView.getContext(), null , false);
xWalkSettings.setAppCacheEnabled(true);
and then modifying my looped task
public void CheckConnectivity(boolean recursiveTask){
cm = (ConnectivityManager) getSystemService(Activity.CONNECTIVITY_SERVICE);
if(cm != null && cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isConnected()){
xWalkSettings.setCacheMode(WebSettings.LOAD_DEFAULT);
}
else{
xWalkSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
}
if(recursiveTask){
CheckConnectivityTask();
}
}
However any attempt to load cached pages fails with "Internet connection has been lost" alert dialogue. Am I instantiating the XWalkSettings instance incorrectly, or is there another way of achieving this?
I found a way from this link. And changed it slightly. Basically need to use reflection to get access to a non public (afaik) method.
Method ___getBridge;
try {
___getBridge = XWalkView.class.getDeclaredMethod("getBridge");
___getBridge.setAccessible(true);
XWalkViewBridge xWalkViewBridge = null;
xWalkViewBridge = (XWalkViewBridge)___getBridge.invoke(mainWebView);
xWalkSettings = xWalkViewBridge.getSettings();
xWalkSettings.setAppCacheEnabled(true);
} catch (NoSuchMethodException e1) {
// TODO Auto-generated catch block
//e1.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
}
If there's a nicer, cleaner way of doing this I'd love to know :)
Crosswalk didn't expose setCacheMode API before, but it has been exposed recently, please see this JIRA, https://crosswalk-project.org/jira/browse/XWALK-6832
It should be available in Crosswalk 21, you can use it like below:
mXWalkView.getSettings().setCacheMode(XWalkSettings.LOAD_NO_CACHE);
So, enjoy it.. :)
I want to be able to turn off overscroll (the glowing effect when reaching the top or bottom of a page in 2.3+) however I also want my code to run in older versions of android that don't even have overscroll functionality. As per the documentation here: Android Backwards Compatibility I am using reflection in my custom webview class to call setOverScrollMode however everytime I call this on a device running 2.3.4, I get a NoSuchMethodException. Any idea why I can't retrieve this method?
Strangely, if I just call setOverScrollMode without any reflection, it works, so the method is definitely there.
public class MyWebView extends WebView{
public void compatibilitySetOverScroll(){
try {
Method mWebview_SetOverScroll = WebView.class.getMethod("setOverScrollMode", new Class[] { Integer.class } );
/* success, this is a 2.3+ */
if (mWebview_SetOverScroll != null) {
try {
mWebview_SetOverScroll.invoke(this, 2);
} catch (InvocationTargetException ite) {
throw new RuntimeException(ite.getCause());
} catch (IllegalAccessException ie) {
System.err.println("unexpected " + ie);
}
}
} catch (NoSuchMethodException nsme) {
/* failure, must be older device */
}
}
}
Try Integer.TYPE instead of Integer.class
More correct version:
public static void disableOverscroll(View view) {
Class<?> viewCls = view.getClass();
try {
Method m = viewCls.getMethod("setOverScrollMode",
new Class[] { int.class });
int OVER_SCROLL_NEVER = (Integer) viewCls.getField(
"OVER_SCROLL_NEVER").get(view);
m.invoke(view, OVER_SCROLL_NEVER);
} catch (Exception e) {
// swallow
}
}
another way :
try
{
Class<?> myTarget = Class.forName("android.widget.HorizontalScrollView");
Method myMethod = myTarget.getDeclaredMethod("setOverScrollMode", Integer.TYPE);
myMethod.invoke(scrollView, 2);
}
catch (Exception e)
{
e.printStackTrace();
}
Is it possible to retrieve the time an account was last synchronized, like the system Settings->Accounts&Sync app does? I'm using Android 2.2.
Looking at the 2.2 source for AccountSyncSettings.java, I see the status is retrieved using:
SyncStatusInfo status = ContentResolver.getSyncStatus(account, authority);
but SyncStatusInfo and getSyncStatus don't seem to be part of the public API (marked with #hide). Is there some other way to get at this info?
You can use reflection to achieve this purpose.Here is my code to implement this
private long getLasySyncTime() {
long result = 0;
try {
Method getSyncStatus = ContentResolver.class.getMethod(
"getSyncStatus", Account.class, String.class);
if (mAccount != null && mSyncAdapter != null) {
Object status = getSyncStatus.invoke(null, mAccount,
mSyncAdapter.authority);
Class<?> statusClass = Class
.forName("android.content.SyncStatusInfo");
boolean isStatusObject = statusClass.isInstance(status);
if (isStatusObject) {
Field successTime = statusClass.getField("lastSuccessTime");
result = successTime.getLong(status);
TLog.d(WeixinSetting.class, "get last sync time %d", result);
}
}
} catch (NoSuchMethodException e) {
} catch (IllegalAccessException e) {
} catch (InvocationTargetException e) {
TLog.d(WeixinSetting.class, e.getMessage() + e.getCause().getMessage());
} catch (IllegalArgumentException e) {
} catch (ClassNotFoundException e) {
} catch (NoSuchFieldException e) {
} catch (NullPointerException e) {
}
return result;
}
The Settings app uses ContentResolver.getSyncStatus(account, authority). However, this is not part of the public API. You can use it, but it could break with any future release.
