I am starter at Android, I found this library for deep links, and it's just not working.
After the example beneath, I didn't receive the deep link.
I annotate my activity as in the GitHub example
#DeepLink("http://example.com/{id}")
public class SplashActivity extends AppCompatActivity {
I setup manifest.xml
<activity
android:name="com.example.SplashActivity"
android:exported="true"
android:label="#string/app_name"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" android:host="example.com" />
<data android:scheme="http"/>
</intent-filter>
</activity>
And I setup the rest on onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_screen);
if (getIntent().getBooleanExtra(DeepLink.IS_DEEP_LINK, false)) {
Bundle parameters = getIntent().getExtras();
Log.d("TAG", "Deeplink params: " + parameters);
String idString = parameters.getString("id");
Log.d("id", idString);
link = idString;
}
I trigger the deep link via adb
adb shell am start -W -a android.intent.action.VIEW -d "http://example.com/123"

App successfully launched Snapchat app but it's not login it shows an error Something is wrong Here is my complete code and other implementation. This is the official documentation that I have followed https://kit.snapchat.com/docs/login-kit-android

i have 2 issues:
the major issue is that if the app is not installed on my phone (android), then the branch link sents me to install it via play store, but then after i install and open it from there i dont have the deep link data.
if the app is already installed and i click the branch link, i need to choose between to open it via chrome or via app,
if i choose chrome -> again no deep link data.
this is the source code:
MainApp.java
public class MainApp extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override public void onStart() {

try {
Branch.sessionBuilder(this).withCallback(new Branch.BranchReferralInitListener() {
#Override
public void onInitFinished(JSONObject referringParams, BranchError error) {
if (error == null) {
// option 3: navigate to page
Intent intent = new Intent(MainApp.this, Main2Activity.class);
startActivity(intent);
} else {
Log.i("BRANCH SDK", error.getMessage());
}
}
}).withData(this.getIntent().getData()).init();
}
catch (Exception e) {
e.printStackTrace();
}
}
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
try {
setIntent(intent);
// if activity is in foreground (or in backstack but partially visible) launching the same
// activity will skip onStart, handle this case with reInitSession
Branch.sessionBuilder(this).withCallback(branchReferralInitListener).reInit();
}
catch (Exception ignored) { }
}
private Branch.BranchReferralInitListener branchReferralInitListener = new Branch.BranchReferralInitListener() {
#Override
public void onInitFinished(JSONObject linkProperties, BranchError error) {
// do stuff with deep link data (nav to page, display content, etc)
}
};

The correct Manifest.xml file should be like this -

Also, ensure that you are using the correct API Key with the links you are using. If it's a Live Link, then use the Live API key and vice versa.
I have 2 activity in my app - first and second. Currenly my default is first.
<activity
android:name=".FirstActivity"
android:label="randomlabel"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".SecondActivity"></activity>
Now i want to change default activity so i change like this:
<activity
android:name=".FirstActivity"
android:label="randomlabel"
>
</activity>
<activity android:name=".SecondActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity
and app now didn't work, what is bad here ?
error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{ru.russian.app/ru.russian.app.FirstActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference
Edit2:
FirstActivity
public class FirstActivity extends AppCompatActivity {
Button button10;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
button10.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
goToSecond();
}
});
}
private void goToSecond() {
Intent intent = new Intent(this, SecondActivity.class);
startActivity(intent);
}
}
It looks like from your stacktrace that you forgot to bind the button in FirstActivity. You need to bind it by calling
button10 = (Button) findViewById(R.id.my_button_id);
Replace my_button_id with the id that you set for the button in your activity_first layout.
Try this:
<activity
android:name=".FirstActivity"
android:label="randomlabel">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name=".SecondActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity
it looks like you are trying to set a onClick() listener in your activity on a view that hasn't been initialised correctly.
you need to initialise the button from the inflated view.
add
button10 = (Button) findViewById(R.id.button10);
I have a Parse notification in my app. If I open my app. then it will receive the notification.
If I restart my phone. No notification will be received, until I open my app.
My question is:
How Can I initiate / run, my ParsePushBroadcastReceiver whenever the phone has been restarted. or how can I make this Receiver to be always running even if user close the app / kill the app ?
I though by adding android.intent.action.BOOT_COMPLETED would work. but it don't
Here is my manifest:

Log.d(TAG, "Receiver intent data => " + intent.toString());
}
}//end onReceive
#Override
public void onPushOpen(Context context, Intent intent) {
...
I wouldn't recommend it but you could make an onBacKeyPressed() method and just make it look like the app has been killed.
On the app I am making, on the home menu screen that you get to after the splash screen, when you click one of the buttons, nothing happens. I don't know what the problem is?
Here is the src file, it implements View.OnClickListener:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bPlay:
Intent ourIntentPlay = new Intent(PartyActivity.this, Play.class);
startActivity(ourIntentPlay);
break;
case R.id.bFacts:
Intent ourIntentFacts = new Intent(PartyActivity.this, Facts.class);
startActivity(ourIntentFacts);
break;
case R.id.bInfo:
Intent ourIntentInfo = new Intent(PartyActivity.this, Info.class);
startActivity(ourIntentInfo);
break;
case R.id.bHelp:
Intent ourIntentHelp = new Intent(PartyActivity.this, Help.class);
startActivity(ourIntentHelp);
break;
}
}
And here is the manifest, inside the application tags:
<activity
android:name=".Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Thanks
Are you assigning a listener to your buttons? Do this in your onCreate() method:
findViewById(R.id.bPlay).setOnClickListener(clickListener);
If your activity implements OnClickListener, then clickListener will be this. Do this for all of your buttons.
