I've been reading through some of the other posts about calling an activity in another package and it looks like I'm doing it right but still getting this error from my main activity:
AndroidTestProj1/src/com/testing/androidtest/TestProj1Activity.java:7: error: package com.testing.androidtest2 does not exist
I've declared the other activity in my manifest but it still cannot find it.
====================================
Here's AndroidTestProj1:
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>

and AndroidTestProj1/src/com/testing/androidtest/TestProj1Activity.java:
package com.testing.androidtest;
import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import com.testing.androidtest2.TestProj2Activity;
public class TestProj1Activity extends Activity
{
/** Called when the activity is first created. */
#Override

{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// do some stuff here then call other package activity
Intent i = new Intent(this, TestProj2Activity.class);
startActivity(i);
}
}
Here's AndroidTestProj2: AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
and AndroidTestProj2/src/com/testing/androidtest2/TestProj2Activity.java:
package com.testing.androidtest2;
import android.app.Activity;
import android.os.Bundle;
import com.testing.androidtest2.Helper;

private boolean somekeyvalue = Helper.getSomeKeyValue();
// do stuff with keyvalue
}
And AndroidTestProj2/src/com/testing/androidtest2/Helper.java:
package com.testing.androidtest2;
import android.content.Context;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
public class Helper {
private static final String SOMEKEY = "somekey";
private static SharedPreferences prefs;
public static void init(Context context)
{
prefs = PreferenceManager.getDefaultSharedPreferences(context);
initialize();
}
private static void initialize()
{
SharedPreferences.Editor editor = prefs.edit();
if (!prefs.contains(SOMEKEY)) editor.putBoolean(SOMEKEY, false);
editor.commit();
}
public static boolean getSomeKeyValue()
{
return prefs.getBoolean(SOMEKEY, true);
}
}
It is the same thing which you do in normal scenario but with a little tweak in it. In FirstActivity where ever you want to call other activity from other package, put following code
code
Intent i = new Intent();
i.setClassName("com.CodeArt.finalactivity", "com.CodeArt.finalactivity.FinalActivity");
startActivity(i);
Here com.CodeArt.finalactivity is the package name and com.CodeArt.finalactivity.FinalActivity is full class name.
Now go to the AndroidManifest.xml of the FirstActivity and Add following line
activity android:name=”com.CodeArt.finalactivity.FinalActivity” in application tag.
It will work fine.
Just an assumption, but have you already add your second project into your current one? Otherwise you cannot reach out its class even though you declare them in your manifest.

I transformed my project into a library. This project just displays a blank activity. I imported this library into another project where I want to call it thru the projects main activity but I keep on getting the error below even if I already declared the activity inside the projects manifest.
Unable to find explicit activity class {com.package.name/com.package.name.BatibotActivity}; have you declared this activity in your AndroidManifest.xml?
This is my project manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pak.paks.pocket" >
<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>
<activity
android:name="com.package.name.BatibotActivity"
android:screenOrientation="portrait" >
</activity>
</application>
</manifest>
What am I doing wrong?
edit:
this is my BatibotActivity
package com.package.name;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class BatibotActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_batibot);
}
}
EDIT2
This is the class that is calling the BatibotActivity
package pak.paks.pocket;
import android.content.ComponentName;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void submitBtn(View view) {
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setComponent(new ComponentName("com.package.name",
"com.package.name.BatibotActivity"));
startActivity(intent);
}
}
By the log message, you are trying to open com.package.name/com.package.name.BatibotActivity, but the Activity registered on AndroidManifest.xml is pak.paks.pocket/com.package.name.BatibotActivity.
The first parameter for ComponentName is the package name. This is the correct code:
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setComponent(new ComponentName("pak.paks.pocket", "com.package.name.BatibotActivity"));
startActivity(intent);
Please check your manifest tag's package attr.
<manifest package="com.package.name">
<application>
...
</application>
</manifest>
I'm using intent method to make a simple app that takes you from main screen [with an enter button] to another screen which has three options. Code sourced online and seems to be error free, though my app crashes saying "Unfortunately [yourapp], has stopped" immediately after i press the button which is meant to take to the the other screen.
This is my first activity code:
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity {
Button button;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
}
public void addListenerOnButton() {
final Context context = this;
button = (Button) findViewById(R.id.enterBtn);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, HomeActivity.class);
startActivity(intent);
}
});
}
}`
And this is my landing screen's activity code:
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
public class HomeActivity extends Activity {
Button button;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
}
}
I'm really stuck with this issue and any help would be much appreciated. Many thanks in advance.
Every activity needs to be added in your manifest file under application tag. This seems to be the problem in your case.
Try to post you LogCat so that we might get some more information and if you have not yet added your Activity in the manifest, this is the way of adding it (Activities go under application tag)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.southmp3"
android:versionCode="1"
android:versionName="1.0" >

android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

</intent-filter>
</activity>
<activity
android:name=".HomeActivity"
android:label="#string/app_name" >
</activity>
</application>
all the Activities should be going under the application tag
I had forgotten to register my new activity on the androidmanifest.xml file. That's what sorted my app crash issue.
I am a new android developer and encountered a problem while following the tutorial on Android's site - http://developer.android.com/training/basics/firstapp/starting-activity.html
My program loads on the emulator fine, but when you type something into the EditText and then hit the send button, a window pops up saying "App has stopped working". It seems as though my new activity isn't being created and I'm not sure as to why. I've scoured the web (and my code) to see if I could get a solution but did so to no avail. Any help would be appreciated.
The code for my first activity:
package com.example.appli;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
public class MainActivity extends Activity {
public final static String EXTRA_MESSAGE = "com.example.myapp.MESSAGE";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.testlayout);
//////Button myButton = (Button) findViewById(R.id.my_button); //Told in tutorial to put this in onCreate
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
/** Called when the user selects the Send button */
public void sendMessage(View view) {
// Do something in response to button
Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText editText = (EditText) findViewById(R.id.edit_message);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
The code for my second activity (the one being called)
package com.example.appli;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;
public class DisplayMessageActivity extends Activity{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//get message from intent
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
// Create the text view
TextView textView = new TextView(this);
textView.setTextSize(40);
textView.setText(message);
setContentView(textView);
}
}
The Manifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.appli"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity android:name="com.example.myapp.DisplayMessageActivity" />
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
In AndroidManifest File you have declared incorrect package
change
<activity android:name="com.example.myapp.DisplayMessageActivity" />
to
<activity android:name="com.example.appli.DisplayMessageActivity" />
or just
<activity android:name=".DisplayMessageActivity" />
you have declared only one Activity that's also wrong package name
already your manifest has the package name
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.appli"
so just declare like this
<activity android:name=".DisplayMessageActivity" />
and you need to add this in your manifest also
<activity android:name=".MainActivity />
remove the target SDK version that you mentioned
android:targetSdkVersion="15"
Try this
<activity android:name=".DisplayMessageActivity"/>
Instead of
<activity android:name="com.example.myapp.DisplayMessageActivity" />
in your Manifest.xml file.
You has defined the package package com.example.appli; in your activities.
Why have you defined you activity in manifest like <activity android:name="com.example.myapp.DisplayMessageActivity" />?
Replace this line with
<activity android:name=".DisplayMessageActivity" />.
I want to link my two activites by clicking on a button i have written the following code
public class IHBCAPTUREActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
ImageView iv;
TextView tx;
Button b1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
iv=(ImageView)findViewById(R.id.imageView1);
tx=(TextView)findViewById(R.id.textView1);
b1 = (Button) findViewById(R.id.button1);
b1.setOnClickListener(this);
}
#Override
public void onClick(View v) {
Intent calIntent;
**calIntent = new Intent(IHBCAPTUREActivity.this, LoginActivity.class);**
startActivity(calIntent);
}
}
error cumes in this line
calIntent = new Intent(IHBCAPTUREActivity.this, LoginActivity.class);
for LoginActivity.class that
LoginActivity cannot be resolved to a type . How to solve it?
here is the simple code how you can load one activity to another,
i have created two activities like this
FirstActivity.java
package com.rdc;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class FirstActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.first);
Button btnload = (Button) findViewById(R.id.btn);
btnload.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(this, SecondActivity.class);
startActivity(i);
}
}
SecondActivity.java
package com.rdc;
import android.app.Activity;
import android.os.Bundle;
public class SecondActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
}
}
and my manifest file is
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.rdc"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".FirstActivity"
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=".SecondActivity"
android:label="#string/app_name">
<intent-filter>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
try to implement this in your app and let me know if still any doubt is there.
Check whether you have declared LoginActivity in manifest file as:
<activity
android:name="your.package-name.LoginActivity" >
</activity>
You don't have anything wrong in code.
Its know issue that occurs randomly.
solution is to set the target to other API level in project->properties->android, then set it back.then clean you project once.
I think this will refresh the .classpath or some other files, not sure, but it works.
I have some trouble while try using broadcast receiver.
Target:
I have three app which will work next schema
1. First - is broadcast receiver app which will write some data to database when it will get a message.
2. Second - is app android which will send some intent with data which must be saved in database.
3. Third - is widget in home screen which will also send some intent with data which must be saved in database.
So, I make three app on eclipse.
1. BroadcastReceiverExample - broadcast receiver it has next files
package com.test.receive;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class SimpleReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "service get started action", Toast.LENGTH_LONG).show();
Log.e("START","START");
}
}
and the manifest file source
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.test"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<receiver android:enabled="true" android:name=".receive.SimpleReceiver" android:exported="false">
<intent-filter android:priority="999">
<action android:name="com.test.SIMPLE_TEST_SERVICE"></action>
</intent-filter>
</receiver>
</application>
</manifest>
also I create App project (BroadcastSenderExample) in Eclipse
and it has file with next sender code
package com.test.sender;
import com.test.R;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class BroadcastSenderExample extends Activity {
public final static String ACTION="com.test.SIMPLE_TEST_SERVICE";
public final static String TYPE="type";
public final static int START=1;
public final static int STOP=0;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnStart=(Button)findViewById(R.id.btnStart);
btnStart.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent bcIntent=new Intent(ACTION);
sendBroadcast(bcIntent);
}
});
btnEnd=(Button)findViewById(R.id.btnEnd);
btnEnd.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent bcIntent=new Intent(ACTION);
sendBroadcast(bcIntent);
}
});
}
private Button btnStart=null;
private Button btnEnd=null;
}
Then I install first app on device (and emulator try too), and install second app.
And then second app run intent call nothing happen.
What am I doing wrong?
I make two projects with next code
Project one wBRReceiver
File WBRReceiver.java
package com.x.brreceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class WBRReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context arg0, Intent arg1) {
Log.i("THIS IS A TEST RECEIVER","THIS IS A TEST RECEIVER");
Toast.makeText(arg0, "this is a test receiver", Toast.LENGTH_LONG).show();
}
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.x.brreceiver"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<receiver android:name="WBRReceiver">
<intent-filter>
<action android:name="com.x.START"></action>
</intent-filter>
</receiver>
</application>
</manifest>
And project two wBRSender
File WBRSenderActivity.java
package com.x.brsender;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class WBRSenderActivity extends Activity {
private String ACTION_NAME="com.x.START";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent brr=new Intent(ACTION_NAME);
//I can't use this
//brr.setClass(this, WBRReceiver.class);
//Because i just don't have this class in this case
sendBroadcast(brr);
}
}
And manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.x.brsender"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".WBRSenderActivity"
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>
And then I install first app onto emulator, and then run second app. And it works.
Did you look at the logcat output? There's a very good chance it tells you exactly what's wrong.
Without staring at your code too much, it seems that your manifest is broken. In your receiver, you state the android:name is ".receive.SimpleReceiver"... this value (when starting with a .) is not simply "the part that follows the Android package name) -- though it works out that way most of the time. In your case, your Android package is "com.test" however the package containing your receiver is "com.test.receive.SimpleReceiver" and its Java package is "com.test.receive". Try changing your android:name to "com.test.receive.SimpleReceiver".
