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{

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?

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 want to block incoming SMS message as long as my application is running . I could achieve that but the problem is after I close the app or even restart or even uninstall it the user will not be able to receive SMS message anymore . So How can I make the application to block incoming SMS only when it's running and when it gets closed or uninstalled etc.. to stop blocking SMS. Here's my code :
BroadCastReceiver.Java
package com.example.sms;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;
public class BroadCastReceiver extends BroadcastReceiver
{
public void onReceive(Context context, Intent intent)
{
abortBroadcast();
}
}
MainActivity.java
package com.example.sms;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Manifiest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sms"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.RECEIVE_SMS"/>

<receiver android:name=".BroadCastReceiver">
<intent-filter android:priority="2147483647">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
<activity
android:name="com.example.sms.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>
Note: I've tested the application on android 2.2 on my android emulator "Sent SMS messages using Telnet"
Check if your app is running then only abort broadcast receiver else not
//define this variable above onReceive() with default value as false;
boolean appRunningInBack=false;
ActivityManager am = (ActivityManager) mContext.getSystemService(Activity.ACTIVITY_SERVICE);
String packageName = am.getRunningTasks(1).get(0).topActivity.getPackageName();
if(packageName.equalIgnoreCase("your app package name") || appRunningInBack)
{
appRunningInBack=true;
abortBroadCast();
} else {
}
Also add Permission in AndroidManifest.xml
<uses-permission android:name="android.permission.GET_TASKS" />
After this when your app goes in background.or while running .this variable will be true.

You can't instantiate abstract classes. Remove the 'abstract' from "public abstract class MainActivity", which will give you a different error telling you to implement the onClick method. Once you add that method that your app will launch.
I would like to send an array in different application.
So In the first application I have MainActivity. The Activity will start an intent. When I'm trying to make an intent, I found a problem. The problem is ShowArrayActivity "cannot be resolved to a type". Actually ShowArrayActivity class is in another apppication. I have tried to add project in build path, but I have an error message said that a cycle was detected in the build path of project 'sendIntent'..
package com.example.sendintent;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import com.example.sendintent.DisplayMessageActivity;
public class MainActivity extends Activity {
public static final String ARRAYS_COUNT = "com.example.sendintent.MainActivity.ARRAYS_COUNT";
public static final String ARRAY_INDEX = "com.example.sendintent.MainActivity.ARRAY_INDEX";
#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.main, menu);
return true;
}
public void sendMessage(View view)
{
final String data[][] = new String[][]
{{"Car","75","loaded"},
{"Motor","25","loaded"},
{"Truck","30","loaded"},
{"Bike","40","loaded"},
{"Boat","10","loaded"}};
Bundle bundle = new Bundle();
int count = data.length;
bundle.putInt(ARRAYS_COUNT, count);
for (int i = 0; i < count; i++)
bundle.putStringArray(ARRAY_INDEX + i, data[i]);
Intent intent = new Intent(this, ShowArrayActivity.class); ---->ERROR
intent.putExtras(bundle);
startActivity(intent);
}
}
In Manifest I have declare
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sendintent"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
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.sendintent.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="com.example.sendintent.DisplayMessageActivity"
android:parentActivityName="com.example.sendintent.MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.sendintent.MainActivity" />
</activity>
<service android:name="com.example.sendintent.MainActivity" />
<receiver android:name="com.example.receiver.MainActivityReceiver">
<intent-filter>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_COUNT"/>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_INDEX"/>
</intent-filter>
</receiver>
</application>
</manifest>
In another application, I have declare the receiver for the intent. It called MainActivityReceiver
package com.example.receiver;
import java.util.ArrayList;
import com.example.sendintent.MainActivity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MainActivityReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
intent.setClass(context, MainActivity.class);
context.startService(intent);
}
}
I have another class called ShowArrayAcivity:
package com.example.receiver;
import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class ShowArrayActivity extends Activity {
public String[][] data;
public static final String ARRAYS_COUNT = "com.example.sendintent.MainActivity.ARRAYS_COUNT";
public static final String ARRAY_INDEX = "com.example.sendintent.MainActivity.ARRAY_INDEX";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
int count = bundle.getInt(ShowArrayActivity.ARRAYS_COUNT, 0);
ArrayList<String[]> arrays = new ArrayList<String[]>(count);
for (int i = 0; i < count; i++)
arrays.add(bundle.getStringArray(ShowArrayActivity.ARRAY_INDEX + i));
data = arrays.toArray(new String[][]{});
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
In Manifest for receiver application
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.receiver"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
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.receiver.ShowArrayActivity"
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="com.example.sendintent.MainActivity" />
<receiver android:name="com.example.receiver.MainActivityReceiver">
<intent-filter>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_COUNT"/>
<action android:name="com.example.sendintent.MainActivity.ARRAYS_INDEX"/>
</intent-filter>
</receiver>
</application>
</manifest>
In receiver application, It won't show the array from sendIntent application in Interface. I just want to know the way to use broadcast and intent. So if I run in debug mode,in ShowArrayActivity, the variable data will containt the result of the intent.
So my questions is,why I can't use another class when I try to send the intent? Did I forgot something to implement for madethe communication between 2 application?
Intent intent = new Intent(this, ShowArrayActivity.class);
this way you tell activity to find ShowArrayActivity within this Application and launch it. It fails as Application can't find it in it's manifest.
Create Intent with action.
Intent intent = new Intent (NAME_OF_THE_FILTER);
then replace string it second manifest
assuming
public static final String NAME_OF_THE_FILTER = "com.myapp.myfilter"
<intent-filter>
<action android:name="com.myapp.myfilter"/>
</intent-filter>
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.
