I have imported a package which was downloaded from the link "https://github.com/moritz-wundke/android-page-curl", then I created a new project and imported the downloaded package by clicking on "import module". I have added a button inside my new package to open the downloaded package. But its not working. Can someone help. Here is the code
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i;
PackageManager manager = getPackageManager();
try {
i = manager.getLaunchIntentForPackage
("fi.harism.curl");
if (i == null)
throw new PackageManager.NameNotFoundException();
i.addCategory(Intent.CATEGORY_LAUNCHER);
startActivity(i);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}
});
}
Manifest:

i'm a student and i'm working on a mobile app.
The probleme is that my app was working, but now when i click on the button to open another window it closes.
Here is my code:
`
public class MainActivity extends AppCompatActivity {
Button b_inscrire_etudiant;
Button b_inscrire_enseignant;
Button b_inscrire_admin;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b_inscrire_etudiant = findViewById(R.id.b_inscrire_etudiant);
b_inscrire_enseignant = findViewById(R.id.b_inscrire_enseignat);
b_inscrire_admin = findViewById(R.id.b_inscrire_admin);
b_inscrire_etudiant.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this , InscriptionEtudiant.class);
startActivity(i);
}
});
b_inscrire_enseignant.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this , InscriptionEnseignant.class);
startActivity(i);
}
});
b_inscrire_admin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this , InscriptionAdmin.class);
startActivity(i);
}
});
}
}
`
I worked as usual "using Intent" besides it worked well until now.
Here is my Manifest file:
<?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>
</manifest>
ps: I solved the problem, by the way two were missing
Thank you for the answers.
It's true, it was missing a part of the code which was not written in the manifest file
I am working on a simple project which is responsible to launch and quit another installed application (let's call it "abc") on the tablet.
The other application ("abc") is already installed in tablet. I can launch it using Intent. But need to find a way to quit it as well.
Here is the template of my mainActivity.java file.
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final LinearLayout parent = findViewById(R.id.parent);
Button launchApp = (Button) findViewById(R.id.button);
Button quitApp = (Button) findViewById(R.id.button2);
launchApp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.abc");
if (launchIntent != null) {
startActivity(launchIntent);
} else {
Toast.makeText(MainActivity.this, "There is no package available in android", Toast.LENGTH_LONG).show();
}
}
});
quitApp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Add code to close the installed app on tablet ("com.abc")
}
});
}
}
This is also my activitymanifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

tools:ignore="ProtectedPermissions" /!-->
<uses-permission android:name="android.permission..com.abc"></uses-permission>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"

<activity android:name=".MainActivity">

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<queries>
<package android:name="com.abc"/>
</queries>
</manifest>
I have tried the suggestions in the following threads, but none of them worked for me:
How to get PID from package name?
Followed the suggestion of this thread, but when I tried to list all running applications, it only reported the running application (the one through which i want to close the other application)
Android Permission Denial: forceStopPackage()
this is my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.openboot">

My BroadcastReceiver that "receives" the boot completed 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, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
My MainActivity that I need to open:
public class MainActivity extends AppCompatActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
I need MainActivity to open when the phone turns on, but I don't see the way to do it.
public class MainActivity extends AppCompatActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new
Intent(getApplicationContext,StartAppOnBoot.class);
sendBroadcast(intent);
}

My app crashes when I try to navigate to another activity. Why does that happen?
I'm able to start the other activity when I launch it at first so there's no problem in the CheckUsernameActivity.
public class CheckNumberActivity extends AppCompatActivity {
EditText phoneNumberEditText;
Button countryCodeButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_check_number);
Button button = (Button) findViewById(R.id.okButton);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
countryCodeButton = (Button) findViewById(R.id.countryCodeButton);
phoneNumberEditText = (EditText) findViewById(R.id.phoneNumberEditText);
Log.v("areaCode", countryCodeButton.getText().toString());
Log.v("phoneNumber", phoneNumberEditText.getText().toString());
Intent k = new Intent(CheckNumberActivity.this, CheckUsernameActivity.class);
startActivity(k);
}
});
}
}
Try This way. I think it will help you.
public class CheckNumberActivity extends AppCompatActivity {
EditText phoneNumberEditText;
Button countryCodeButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_check_number);
Button button = (Button) findViewById(R.id.okButton);
countryCodeButton = (Button) findViewById(R.id.countryCodeButton);
phoneNumberEditText = (EditText) findViewById(R.id.phoneNumberEditText);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.v("areaCode", countryCodeButton.getText().toString());
Log.v("phoneNumber", phoneNumberEditText.getText().toString());
Intent k = new Intent(CheckNumberActivity.this, CheckUsernameActivity.class);
startActivity(k);
}
});
}
}
I didn't have my new activity defined in my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dimsumdev.runk" >
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"

<action android:name="android.intent.action.DEFAULT" />

then when i press f8 a i get : ZygoteInit$methodandargscaller.run() source not found

I have tried cleaning the project, re-writing the manifest and everything i can possible think of. It works if i comment out the links to the buttons in the code and leave them in the manifest but the moment i uncommnet them i get these errors, please help!!!
The problem is that the activity throw exception.
eclipse looks for the source code in android SDK and can't find it.
Just debug your code and find out where the code throw exception.
solved it, feeling pretty stupid now, needed bstart not bcstart when the button is defined.
