After I open my app, it jumps to the accessibility settings. But the onServiceConnected is not called after I have turned on my AccessibilityService (which is called VoiceService).
Could you please tell me what should I do? It seems that the VoiceService fails to start although I enable it in XML. Or I need to bind the MainActivity with the VoiceService in a different way?
AndroidManifest.xml

startActivityForResult(sSettingsIntent,0);

}
This is the answer:
in the voice_config.xml
android:settingsActivity="com.example.android.accessibility.ServiceSettingsActivity" should be modified as your own activity name.

I am designing an android application in java and I would like it to launch when the smartphone starts up I of course registered a BroadcastReceiver for the BOOT event of my phone as explained here but it does not work on Android 10 if not for info it worked on Android 4.1.
Can you help me please ?
Here is my code:
Manifest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.openclassrooms.fr.premierprojet">
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<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=".PremiereActivite">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".StartAppOnBoot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
</application>
</manifest>
Classe Main :
package com.openclassrooms.fr.premierprojet;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class PremiereActivite extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Classe Diffuseur :
package com.openclassrooms.fr.premierprojet;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class StartAppOnBoot extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
Intent i = new Intent(context, PremiereActivite.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
}
Cordially.
I tried to do a broadcast receiver dynamically for incoming SMS will show a toast but the app doesn't show anything.
I register the broadcast dynamically in the mainActivity like this.
MainActivity.java
package com.example.smsreader;
import android.content.Intent;
import android.content.IntentFilter;
import android.net.ConnectivityManager;
import android.support.v4.content.LocalBroadcastManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
BroadcastReader reader = new BroadcastReader();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(reader, filter);
}
}
This is brodcast class, the app will show a toast when the phone will receive a SMS but it doesn't
package com.example.smsreader;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class BroadcastReader extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if("android.provider.Telephony.SMS_RECEIVED".equals(intent.getAction())){
Toast.makeText(context, "it is working", Toast.LENGTH_LONG).show();
}
}
}
I don't register anything in the manifest file.
Manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.smsreader">
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.READ_SMS"/>
<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>
</application>
</manifest>
Try the following :
intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
You need to use the following method for registering local broadcastReceiver ;)
LocalBroadcastManager.getInstance(this).registerReceiver(reader, filter)
I am learning the basics of android programming. Now I have made a Life Cycle test. The list activity works fine, but when I attempt to open the Life Cycle test, the app stops and closes. I have got the same problem on several devices. These are my codes:
(Manifest)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

I use Eclipse on Windows 7. Thank you in advance!
Add your LifeCycleTest activity in AndroidManifest.xml
<activity
android:name=".LifeCycleTest"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
Include both your activities inside your Manifest file. It should look something like this.
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".AndroidBasicsStarter"
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=".LifeCycleTest"
android:label="#string/app_name" >
</activity>
</application>
I have been trying so many different things to get this demo running but i couldn't manage to make it run properly..
This is my Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.messagekeeper"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="9" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.messagekeeper.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>
<receiver android:name=".SmsReciever">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
</manifest>
This is my MainActivity class (Done nothing with it):
package com.example.messagekeeper;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
And This is the SmsReciever class:
package com.example.messagekeeper;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.util.Log;
class SmsReciever extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent){
Object[] pdus=(Object[])intent.getExtras().get("pdus");
SmsMessage shortMessage=SmsMessage.createFromPdu((byte[]) pdus[0]);
Log.d("SMSReceiver","SMS message sender: "+
shortMessage.getOriginatingAddress());
Log.d("SMSReceiver","SMS message text: "+
shortMessage.getDisplayMessageBody());
}
}
When i get a message, i want it to see it on my app. In this situation, i mean when i use this codes and run my app on emulator, and send a message from one emulator to another, my app crashes and i get this error: http://puu.sh/1yZub
If you've copied your code exactly as it stands, you might be just missing the public keyword at the beginning.
Change class SmsReciever extends BroadcastReceiver{
to public class SmsReciever extends BroadcastReceiver{
I wrote simple android app with bugs. When open second activity from menu- android stopped apps.
Code:
Manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="10" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".Activit"
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>
<activity android:name=".Activit2"/>
</manifest>
First Activity:
package com.example;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ContextMenu.ContextMenuInfo;
import android.widget.AdapterView.AdapterContextMenuInfo;
public class Activit extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.me, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId()){
case R.id.ok: Activ();
};
return super.onOptionsItemSelected(item);
}
private void Activ(){
Intent inten=new Intent();
inten.setClass(Activit.this, Activit2.class);
startActivity(inten);
}
}
Second Activity with temporary layout(it the same in the first):
package com.example;
import android.app.Activity;
import android.os.Bundle;
public class Activit2 extends Activity{
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
your tag <Activity /> should be in ( not out ) of the tag <application> :
try this :
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".Activit"
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=".Activit2"/> // you should declare your activity Here
</application>
The tag <activity android:name=".Activit2"/> should be inside the <application> tag in your Manifest.xml
Your second activity definition is outside the application definition in your AndroidManifest.xml.
