I am trying to Detecting Incoming Phone Calls In Android

I just want to show a toast when a call is received, But nothing is happening and it doesn't even stop on OnReceive in debugging mode.
I am unable to figure out that why it is not getting stopped at the onReceive. It is just like it is not even receiving an intent .
AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.rajatgupta.broadcastrecieverexample">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="MyReciever">
<intent-filter>
<action android:name="rajat_action">
</action>
</intent-filter>
</receiver>
<receiver android:name=".IncomingCall">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE">
</action>
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
IncomingCall.java
public class IncomingCall extends BroadcastReceiver {
Context mContext;
#Override
public void onReceive(Context context, Intent intent) {
try {
Log.d("Intent", "Intent Detected");
Toast.makeText(context," Receiver start ",Toast.LENGTH_SHORT).show();
}
catch (Exception e){
e.printStackTrace();
}
}
}
What am I doing wrong?
It is no longer enough to just to put the READ_PHONE_STATE permission in the Manifest, you now have to request permissions at runtime.
Permission check:
int permissionCheck = ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_PHONE_STATE);
Request:
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);

AsyncTask Permission denied (missing INTERNET permission?)

I am trying use AsyncTask to extract an image over the internet and display on the RecyclerViewer but I am getting the following error message, which's captured from my Exception in my doInBackground from my RecyclerViewAdapter class:
08-02 00:11:25.608: E/ImageDownload(5753): Download failed: Permission denied (missing INTERNET permission?)
See full version of AsyncTask sub-class below:
class GetImageFromNet extends AsyncTask<String, Void, Bitmap> {
private RVAdapter.PersonViewHolder personViewHolder;
private String url = "http://ia.media-imdb.com/images/M/MV5BNDMyODU3ODk3Ml5BMl5BanBnXkFtZTgwNDc1ODkwNjE#._V1_SX300.jpg";
public GetImageFromNet(RVAdapter.PersonViewHolder personViewHolder){
this.personViewHolder = personViewHolder;
}
protected Bitmap doInBackground(String... params) {
try {
InputStream in = new java.net.URL(url).openStream();
Bitmap bitmap = BitmapFactory.decodeStream(in);
return bitmap;
//NOTE: it is not thread-safe to set the ImageView from inside this method. It must be done in onPostExecute()
} catch (Exception e) {
Log.e("ImageDownload", "Download failed: " + e.getMessage());
}
return null;
}
protected void onPostExecute(Bitmap bitmap) {
if (isCancelled()) {
bitmap = null;
}
personViewHolder.personPhoto.setImageBitmap(bitmap);
}
I have no idea why I am getting above error since I have already added the following permission access in my AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxx" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Please help!
Move your <uses-permission> elements to be immediate children of <manifest>, above your <application> element.
Update your manifest as:-
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxx" >
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

permissions denied when saving image on sdcard

This function is used to save image on sdcard (I have tested it on the emulator only):
public String SaveImage(String URL,String imagename){
Bitmap bitmap = null;
InputStream in = null;
String path = Environment.getExternalStorageDirectory().toString();
File dir = new File(path + "/bh");
if(!dir.exists())
new File(path + "/bh").mkdir();
Log.i("in save()", "after file");
File mImageFile = new File(path+"/bh/"+imagename);
if(mImageFile.exists())
Toast.makeText(mContext, "Saved", Toast.LENGTH_LONG).show();
try{
in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in);
FileOutputStream out = new FileOutputStream(mImageFile);
bitmap.compress(CompressFormat.JPEG, 100,out);
out.flush();
out.close();
in.close();
return imagename+".jpg";
}catch(IOException ex){
Log.e("==== Error in saving image ====",ex.getMessage());
return "";
}
}
I have added the required permissions like below :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="mobile.bh"
android:versionCode="4"
android:versionName="1.0.3" >

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen" >
<activity
android:name="mobile.bh.activities.BHActivity"

<activity
android:name="mobile.bh.activities.SpicesListActivity"
android:screenOrientation="portrait" >
</activity>
<activity android:name=".activities.SpicesCategoriesActivity" >
</activity>
<activity android:name=".activities.CategoryActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
You also need to use the Internet permission since you're connecting to the internet.
<uses-permission android:name="android.permission.INTERNET" />
Does your emulator support SDCard ?
Have a look at this great answer, it might be the issue https://stackoverflow.com/a/11468278/1635817

IntentService is not being called

I am trying to send an Intent from the onCreate in an Activity to start an IntentService. However the IntentService's onHandleIntent is never being received. I have tried changing around the Manifest with Intent-filters but nothing seems to be working. No exceptions are being thrown, but the IntentService is simply not called.
Here is the onCreate
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
db = new TwitterDB(this);
String[] columns = new String[1];
columns[0] = TwitterDB.TEXT;
tAdapter = new SimpleCursorAdapter(this, 0, null, columns, null, 0);
tweets = (ListView)findViewById(R.id.listtwitter);
tweets.setAdapter(tAdapter);
Intent intent = new Intent(this, SyncService.class);
intent.putExtra("action", SyncService.TWITTER_SYNC);
this.startService(intent);
}
Here is the creator and onHandleIntent of the IntentService class, I know it is not being called because logcat never shows "Retrieved intent". The constructor is not called either (There was a log call in there, but I removed it.
public SyncService(){
super("SyncService");
twitterURI = Uri.parse(TWITTER_URI);
Log.i("SyncService", "Constructed");
}
#Override
public void onHandleIntent(Intent i){
int action = i.getIntExtra("action", -1);
Log.i("SyncService", "Retrieved intent");
switch (action){
case TWITTER_SYNC:
try{
url = new URL(twitterString);
conn = (HttpURLConnection)url.openConnection();
syncTwitterDB();
conn.disconnect();
}catch(MalformedURLException e){
Log.w("SyncService", "Twitter URL is no longer valid.");
e.printStackTrace();
}catch(IOException e){
Log.w("SyncService", "Twitter connection could not be established.");
e.printStackTrace();
}
break;
default:;
// invalid request
}
}
And here is the Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<service android:name="SyncService"/>
</activity>
</application>
</manifest>
Move your service declaration outside of the scope of the TwitterTwoActivity in the XML file, as I have done here:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="SyncService"/>
</application>
</manifest>
You need to define the path to the service in your manifest, simply putting the name is not sufficient.
Change
<service android:name="SyncService"/>
to
<service android:name=".SyncService"/>
if SyncService is in the root of your package, add respective folder before .SyncService if needed.

Selecting & Calling numbers

I have a few numbers in an activity which I would like to be-able to make selectable, like a hyperlink. When the number is pressed it should call the number. I have checked the Android API but wasn't successful.
Anyone have any ideas?
Code for the button from the comment below is:
DialButton=(Button)findViewById( R.id.dialbutton );
DialButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
if(number!=null){
try {
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + number.getText())));
} catch (Exception e) {
e.printStackTrace();
}
}//if
}
});
So what gives? Also in the "AndroidManifest.xml" file I specified the permissions like this:
<uses-permission android:name="android.permission.CALL_PRIVILEGED" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".main"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Is this wrong? Is the permission in the wrong place?
<TextView
android:text="+1........"
android:autoLink="phone" />
http://developer.android.com/reference/android/widget/TextView.html#attr_android:autoLink
Also, don't forget to add a corresponding permission to manifest file
<uses-permission android:name="android.permission.CALL_PHONE" />
