I'm making a pdf file viewer app with this library. I applied other things successfully, but I'm continuously failing to link the app with "Complete action using" list of Android.
First, init() method of the library is as follows(MainActivity.java):
private void init() {
lv_pdf = (ListView)findViewById(R.id.lv_pdf);
dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath());
fn_permission();
lv_pdf.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(getApplicationContext(), PdfActivity.class);
intent.putExtra("position", i);
startActivity(intent);
Log.e("Position", i + "");
}
});
}
Second, AndroidManifest.xml file is as follows:
<activity
android:name=".MainActivity"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".PdfActivity"
android:screenOrientation="portrait">
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
MainActivity.java defines permission and start screens of the app, and PdfActivity.java shows content of the pdf files.
The Problem:
init() method have a implicit intent with getApplicationContext(). How to I link this to intent filter in AndroidManifest.xml file? I want to launch the app through "Complete action using" screens.
Too can you use it
Intent intent = new (this, PdfActivity.class);
Instead of getApplicationContext() use MainActivity.this

My question is how to start app A within app B that appears app A is within app B through deep linking?
In the first picture below, the Debug app appears as a separate app from Slack (new code, Firebase deep linking). In the 2nd picture, the Debug app appears to be within the Slack app (old code, Android deep linking). I want to use Firebase deep linking and show the Debug app within other apps (Slack, Gmail etc).
Can anyone please go through my code below and let me know how I can achieve this?
Old code, Android deep linking:
AndroidManifest
<activity
android:name=".activity.SplashScreenActivity"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme">
<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" />
<!-- Accepts URIs that begin with "abc://flights” -->
<data
android:host="sales"
android:scheme="abc" />
<data
android:host="deals"
android:scheme="abc" />
</intent-filter>
</activity>
Activity:
Intent intent = new Intent(SplashScreenActivity.this, BottomNavBarActivity.class);
//Deep Linking Content
Uri deepLinkData = getIntent().getData();
if (deepLinkData != null) {
intent.putExtra(EXTRA_DEEP_LINK, deepLinkData.getHost());
}
startActivity(intent);
overridePendingTransition(R.anim.splash_fade_in, R.anim.splash_fade_out);
finish();
New Code, Firebase deep linking:
AndroidManifest:
<activity
android:name=".activity.SplashScreenActivity"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme">
<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:host="abc.app.goo.gl"
android:scheme="http"/>
<data
android:host="abc.app.goo.gl"
android:scheme="https"/>
</intent-filter>
</activity>
Activity:
FirebaseDynamicLinks.getInstance()
.getDynamicLink(getIntent())
.addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
#Override
public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {
// Get deep link from result (may be null if no link is found)
Uri deepLink = null;
if (pendingDynamicLinkData != null) {
// Start the activity through intent, same as before.
}
}
})
.addOnFailureListener(this, new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.v(TAG, "Firebase deep link failure");
}
});
Its dependent on the app which sends the intent, for example whether they pass FLAG_ACTIVITY_NEW_TASK or not. I suspect the difference here is how Slack is handling the links - they may treat web URLs differently than other format ones (your old links have non-standard schemes).
Create a method openApp(), and call it accorrding to your need.
public void openAnApp()
{
Boolean flag=false;
try{
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
final PackageManager packageManager = getActivity().getPackageManager();
Intent intent1 = new Intent(Intent.ACTION_MAIN, null);
intent1.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> resInfos = packageManager.queryIntentActivities(intent1, 0);
ActivityInfo activity = null;
//getting package names and adding them to the hashset
for(ResolveInfo resolveInfo : resInfos) {
System.out.println("apap="+resolveInfo.activityInfo.packageName);
if(resolveInfo.activityInfo.packageName.equals("your.app.packagename"))
{
flag = true;
activity = resolveInfo.activityInfo;
break;
}
}
if (flag) {
// final ActivityInfo activity = app.activityInfo;
final ComponentName name = new ComponentName(activity.applicationInfo.packageName,activity.name);
intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setComponent(name);
getActivity().startActivity(intent);
//startActivity(Intent.createChooser(intent , "Send image using.."));
} else {
Uri uri=Uri.parse("market://details?id=your.app.packagename");
Intent goToMarket=new Intent(Intent.ACTION_VIEW,uri);
try{
startActivity(goToMarket);
}catch(ActivityNotFoundException e){
Toast.makeText(getActivity(),"Couldn't launch the market",Toast.LENGTH_SHORT).show();
}
}
} catch (Exception e) {
Toast.makeText(getActivity(), "Something went wrong", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
I have StartActivity and MainActivity, in manifest scheme is already set.
<activity
android:name=".StartActivity"
android:label="#string/app_name"
android:theme="#style/AppThemeNoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<data android:scheme="myApp" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:launchMode="singleTask"
android:parentActivityName=".StartActivity" />
StartActivity:
public class StartActivity extends InstrumentedActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_start);
if (isLogin) {
Intent intent = new Intent(context, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
}
}
The original design is after user pressed the url in browser, it open StartActivity and then go to MainActivity when user logined.
This works correctly in the first time (App is killed and user pressed the url).
But while the app is in the background (in MainActivity), after user press the url, it didn't go through StartActivity but only onResume of MainActivity.
Anyone know the reason? and how to make sure it go to StartActivity? Thanks.
when you open your Activity first time from URL ,that time Activity created so onCreate() method called .But if your Activity is in Background then
onNewIntent() will be called so Override this method And put you code here .
Add below method : IN MainActivity
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
// add your code here
}
In Manifest :
<activity
android:name=".MainActivity"
android:launchMode="singleTask"
/>
Start Activity :
Intent intent = new Intent(context, MainActivity.class);
startActivity(intent);
if you want pass any input value then you may pass in Intent through Bundle ,that is received into onNewIntent(Intent intent) ,and you can get just like we get data from Intent send from one Activity to next activity.
I have an application named as "App" and another application named as "App1", I have a button in "App" when I click that button I want to open "App1", for this I am using Intent but it does not open "App1".Please help
here is my code for button in "App":-
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.app);
init();
}
public void init(){
mTranslucentBtn = (Button) findViewById(R.id.button);
mTranslucentBtn.setAlpha(0.7f);
mTranslucentBtn.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v){//calling an activity using <intent-filter> action name
startNewActivity(MainActivity.this,"com.example.devui1.rewardapp");
}
});
}
public void startNewActivity(Context context, String packageName) {
Intent intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
if (intent == null) {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + packageName));
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
In order for getLaunchIntentForPackage() to work, that package needs to have an Activity that is suitable for being launched as an entry point into that app. The documentation includes this:
The current implementation looks first for a main activity in the category CATEGORY_INFO, and next for a main activity in the category CATEGORY_LAUNCHER. Returns null if neither are found.
This suggests you need one of the following on an Activity in your other package:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.INFO" />
</intent-filter>
Or
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
If that's not something you want, then you could try creating your own custom action string and using that to launch an activity exposing that specific action:
<intent-filter>
<action android:name="your.package.ACTION_NAME" />
</intent-filter>
public void startActivityWithPrivateAction(Context context, String packageName) {
Intent intent = new Intent("your.package.ACTION_NAME");
intent.setPackage(packageName);
List<ResolveInfo> activities = context.getPackageManager().queryIntentActivities(intent, 0);
if (activities.isEmpty() {
// no suitable activity was found; open the market instead.
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + packageName));
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
I'm new in this world. I have a problem when I use startActivity(intent).
This is the Manifest:
<activity
android:name="com.example.counter.Splash"
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.counter.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
And this is the code:
public class Splash extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread timer = new Thread(){
public void run()
{
try
{
sleep(5000);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
finally
{
Intent i=new Intent ("com.example.counter.MainActivity");
startActivity(i);
}
}
};
timer.start();
}
I'd want to show Splash activity for 5 seconds and then show MainActivity.

There are two ways of doing what you are trying to do.
Using an implicit Intent
Using an explicit Intent
Refer Intent Types
Implicit Intent
Declare Intent Filters for your Activity in your AndroidManifest.xml. By doing that the Android system understands what kind of Intents your component(in this case your MainActivity) can handle.
<activity
android:name="com.example.counter.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.example.counter.MainAction" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<activity>
Now you will be able to launch your Activity with the same Intent
Intent i=new Intent ("com.example.counter.MainAction");
startActivity(i);
Such implicit Intents are used when you don't explicitly know which Activity has to be started and you want the Android system to decide which component to start. If the system finds multiple components which can handle your Intent, it will allow the user to choose.
Note: it is possible that there are no applications that can handle your intent. In this case, your application will crash when you invoke startActivity(). To avoid this, before calling startActivity() you should first verify that there is at least one application registered in the system that can handle the intent. To do this use resolveActivity() on your intent object.
Explicit Intent
In your case, you should use an explicit Intent as you already know which Activity you want to start. So create an Intent by passing the context and the component(Activity) class you want to start.
Intent i=new Intent (this,MainActivity.class);
startActivity(i);
You have to reference the class you want to start. So you'd need something like:
Intent newAct = new Intent(this, Splash.class);
startActivity(newAct);
What you're passing is an Action that is not understood as a class name.
I guess, Splash is your Launcher Activity, make following changes in your manifest file:
<activity
android:name="com.example.counter.Splash"
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.counter.MainActivity"
android:label="#string/app_name" >
</activity>
Make your activity this way:
public class Splash extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
/*Splach screen that display for 5 seconds when app start*/
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent i = new Intent(Splash.this, MainActivity.class);
startActivity(i);
finish();
}
}, 5000);
}
}
I hope this should solve your problem now.
I think you should be able to use (implicit Intent):
Intent i=new Intent ("com.example.counter.MainActivity");
There is no reason to change it to (explicit intent):
startActivity(new Intent(mContext, MainActivity.class));
but then you need to change the action in intent filterof MainActivity from:
<action android:name="android.intent.action.MAIN" />
to:
<action android:name="com.example.counter.MainActivity"/>
You need to declare an activity in manifest file.
Like this:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".FirstActivity"
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>
<activty
android:name="com.example.counter.MainActivity"/>
</application>
Hope it helps.
i think it is better if you use Handler put this code at the splash Activity at the onCreate
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
finish();
}
}, 1500);
and if you want to open it one time it is good to use SharedPreferences
I am trying to show a dialog when picture taken so I setup a broadcast receiver on picture taken by default camera app.
I read that I need to call an activity to achieve that. I setup the activity so the theme in the manifest is like transparent
android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen
here is my code
public class CameraEventReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Cursor cursor = context.getContentResolver().query(intent.getData(), null,null, null, null);
cursor.moveToFirst();
String image_path = cursor.getString(cursor.getColumnIndex("_data"));
Toast.makeText(context, "New Photo is Saved as : -" + image_path, Toast.LENGTH_SHORT).show();
Intent i = new Intent(context, DialogActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
The problem is that my main app activity is being displayed behind the Dialog activity so that the main activity is shown. I just want the dialog activity to be displayed on top of the picture.
Is there a way to fix that?
Thank you
EDIT: As requested, my manifest:
<application
android:allowBackup="true"
android:name="MyApplication"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.xx.xx.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=".DialogAcitivity" android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen"
android:label="#string/app_name">

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

My code for button, basically ask the user for a value:
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Intent intent = getIntent();
promptUser();
}
private void promptUser() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
final EditText input = new EditText(this);
builder.setMessage(R.string.msg)
.setCancelable(false)
.setView(input)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString();
storeValue(value);
dialog.dismiss();
}).setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show();
}
the reason your app's activity shows behind the dialog is because android's switching the entire activity task. your dialog activity was (i'm assuming) started in the same task as your other activities.
what you want is to give your dialog activity a different task affinity than the (default) affinity of your other activities.
<activity
...
android:taskAffinity="com.foo.bar.myaffinity"/>
now this activity won't be launched into the same task as the rest of your activities, and when you start it, those other activities won't show behind it.
Check this post
What you want is to get your image from the result, then display it in a layout in some activity. Once the image is displayed, launch your dialog.
