How to use intent for sharing gallery picture to application - android

I have added my application to the share icon on top in the gallery, but so far it only opens my application, but how do I send the picture URI and stuff to my application? I understand I have to use intent? Are there any guides around I can look at? The easy-share-action guide on google website isn't helping me much here.

Try this way:
<activity
android:name="yourActivity"
android:icon="#drawable/ic_launcher"
android:label="test">
<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.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND_MULTIPLE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
</activity>
Handle the Incoming Content
void onCreate (Bundle savedInstanceState) {
...
// Get intent, action and MIME type
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
if (Intent.ACTION_SEND.equals(action) && type != null) {
if ("text/plain".equals(type)) {
handleSendText(intent); // Handle text being sent
} else if (type.startsWith("image/")) {
handleSendImage(intent); // Handle single image being sent
}
} else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
if (type.startsWith("image/")) {
handleSendMultipleImages(intent); // Handle multiple images being sent
}
} else {
// Handle other intents, such as being started from the home screen
}
...
}
void handleSendText(Intent intent) {
String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
if (sharedText != null) {
// Update UI to reflect text being shared
}
}
void handleSendImage(Intent intent) {
Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
if (imageUri != null) {
// Update UI to reflect image being shared
}
}
void handleSendMultipleImages(Intent intent) {
ArrayList<Uri> imageUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
if (imageUris != null) {
// Update UI to reflect multiple images being shared
}
}
For more information go to Receiving Simple Data from Other Apps and Sending Simple Data to Other Apps

To handle an image in your Activity you need to check if the intent has the image.
Intent intent = getIntent();
Bundle extras = intent.getExtras();
String action = intent.getAction();
if (Intent.ACTION_SEND.equals(action)) {
if (extras.containsKey(Intent.EXTRA_STREAM)) {
// Get resource path of the stream, which in this case will be the image
}
}
Furthermore you need to add to your manifest that you want to filter on these sharing image intents.
<activity android:name=".Theme"
android:label="YourImageActivity">
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
</activity>

flutter how to open txt file with open with dialog to specific page?

I'm new on flutter and never used intent filter. so far I have everything working in my app. but I'm stuck in importing the file to app by open with dialog. I need the user when it click on the file it will go to the page and display the information in the file. I'm using ImportFile plugin and it work fine but it make it harder for the users to put the file they receive.
my app is list it in the open with dialog but when i click it, it just open the app I want it to open the app and view the text in the view text page not the homepage
AndroidManifest.xml
<
intent-filter>

}
Thank you in advance
FlutterView has a setInitialRoute method you can use to specify a non-default route on launch.

Android deep linking is not working

Android deep linking is not working
===================================
Android link:-notification://id=notificationid
1:-In manifest
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="id"
android:scheme="notification" />
</intent-filter>
2:-and coding side
#Override
protected void onResume() {
super.onResume();
Intent intent = getIntent();
String string=intent.getAction();
Uri data = intent.getData();
Log.d("hello","cgbdsuyfdkv");
}
but its not working please any body can help me !!!!!
you can simply modify your url
Android link:-notification://id=notificationid instead of
Android link:-notification://page?id=notificationid //page is host name
I tried a lot and find out this is working for me.
manifest code
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="page"
android:scheme="notification" />
</intent-filter>
2.java code #get your notification id here
Intent intent = getIntent();
String string = intent.getAction();
Uri data = intent.getData();
if (data != null) {
String path = data.getPath();
String path1 = data.getPath();
providerUrl = intent.getData().toString();
UrlQuerySanitizer sanitizer = new UrlQuerySanitizer();
sanitizer.setAllowUnregisteredParamaters(true);
sanitizer.parseUrl(providerUrl);
String id = sanitizer.getValue("id");
if (id != null)
Log.d("notification id", id);
}
Add onNewIntent() method to your Activity and then use intent object which is variable in OnNewintent() method , which has updated method.
onNewIntent() is meant as entry point for singleTop or singleTask activities which already run somewhere else in the stack and therefore can't call onCreate(). From activities lifecycle point of view it's therefore needed to call onPause() before onNewIntent(). I suggest you to rewrite your activity to not use these listeners inside of onNewIntent(). For example most of the time my onNewIntent() methods simply looks like this:
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
//use this intent object to get notificationid for second time
}
1st step:
<intent-filter>
<data android:scheme="your_uri_scheme" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
2nd step:
Uri data = this.getIntent().getData();
if (data != null && data.isHierarchical()) {
String uri = this.getIntent().getDataString();
Log.i("MyApp", "Deep link clicked " + uri);
}
I think you Intent Filter is incomplete
<!-- To open app using link -->
<intent-filter>
<action android:name="android.intent.action.VIEW"></action>
<category android:name="android.intent.category.DEFAULT"></category>
<category android:name="android.intent.category.BROWSABLE"></category>
<data android:scheme="http"
android:host="yourdomain.com"
android:pathPrefix="/someurlparam">
</data>
</intent-filter>

How to create an android gallery app

I have created a gallery app. It opens images and photos but System isn't get it as a gallery app. Could anyone help me to set it as a gallery app?
Thank you!
update your manifest, This will tell other apps to receive content
<activity android:name=".ui.MyActivity" >
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND_MULTIPLE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
Handle the Incoming Content.
void onCreate (Bundle savedInstanceState) {
// Get intent, action and MIME type
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
if (Intent.ACTION_SEND.equals(action) && type != null) {
if ("text/plain".equals(type)) {
handleSendText(intent); // Handle text being sent
} else if (type.startsWith("image/")) {
handleSendImage(intent); // Handle single image being sent
}
} else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
if (type.startsWith("image/")) {
handleSendMultipleImages(intent);
// Handle multiple images being sent
}
} else {
// Handle other intents, such as being started from the home screen
}
}
void handleSendText(Intent intent) {
String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
if (sharedText != null) {
// Update UI to reflect text being shared
}
}
void handleSendImage(Intent intent) {
Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
if (imageUri != null) {
// Update UI to reflect image being shared
}
}
void handleSendMultipleImages(Intent intent) {
ArrayList<Uri> imageUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
if (imageUris != null) {
// Update UI to reflect multiple images being shared
}
}
official docs:
https://developer.android.com/training/sharing/receive.html
You should use Intents and Intents Filters
In the link above you should read about "Receiving an implicit intent"
To advertise which implicit intents your app can receive, declare one or more intent filters for each of your app components with an element in your manifest file. Each intent filter specifies the type of intents it accepts based on the intent's action, data, and category. The system delivers an implicit intent to your app component only if the intent can pass through one of your intent filters.
<activity android:name="ShareActivity">
<intent-filter>
<action android:name="android.intent.action.SEND"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/plain"/>
</intent-filter>
</activity>
^ the code above (taken from the documentation) show how to make sure your app open when other activity use SEND intent.
change the action and mimeType to get the resault you want (sending photo?, display photo? etc).

How to get intent filter MimeType

I have the following filters in my application. I want to be able to launch the same app using three different mimeTypes.
Later on I read the NDEF message, but how can I check what mime type was used to launch the app so I can handle the NDEF message data accordingly?
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/product" />
</intent-filter>
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/pesticide" />
</intent-filter>
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/seed" />
</intent-filter>
Here is a simplified version of how I handle csv files and text files in my app. I hope this help:
#Override
public void onNewIntent(final Intent intent)
{
super.onNewIntent(intent);
String type = intent.getType();
String action = intent.getAction();
if ("text/csv".equals(type) || "text/comma-separated-values".equals(type))
{
// Handle CSV file being sent
handleSendCSV(intent);
}
else if("text/plain".equals(type) && Intent.ACTION_SEND.equals(action))
{
// Handle plaintext sent
handlePlainText(intent);
}
else
{
//Alert of some error
doAlertDialog("Error.", "Invalid file type.");
}
}
Edit-
Added:
String action = intent.getAction();
So the code would be complete.

Passing data from one app to another one [duplicate]

This question already has answers here:
launch activities from different package
(5 answers)
Closed 9 years ago.
I have 2 android apps:
app1 - Activity11 --> Activity12 --> Activity13
app2 - Activity21 --> Activity22 --> Activity23
I want to pass from one app to the second Activity of the other one, passing some datas.
app1 - Activity11 -->(switch to app2)--> Activity22 --> Activity23
What steps have i to follow? Do you know some tutorial?
I haven't write code for now, because I don't know where to start.
Thanks in advance.
You need to look into android Intents and Intent Filters. Check this training article for example.
This blog post can also be an interesting read.
A quick example for sending text (other types are in the links on top);
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(sendIntent);
And for receiving:
void onCreate (Bundle savedInstanceState) {
...
// Get intent, action and MIME type
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
if (Intent.ACTION_SEND.equals(action) && type != null) {
if ("text/plain".equals(type)) {
handleSendText(intent); // Handle text being sent
} else if (type.startsWith("image/")) {
handleSendImage(intent); // Handle single image being sent
}
} else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
if (type.startsWith("image/")) {
handleSendMultipleImages(intent); // Handle multiple images being sent
}
} else {
// Handle other intents, such as being started from the home screen
}
...
}
void handleSendText(Intent intent) {
String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
if (sharedText != null) {
// Update UI to reflect text being shared
}
}
void handleSendImage(Intent intent) {
Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
if (imageUri != null) {
// Update UI to reflect image being shared
}
}
void handleSendMultipleImages(Intent intent) {
ArrayList<Uri> imageUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
if (imageUris != null) {
// Update UI to reflect multiple images being shared
}
}
You'll have to update the manifest also:
<activity android:name=".ui.MyActivity" >
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND_MULTIPLE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
</activity>
