                Here are the basic queries & their solutions related to android programming.  There are sample methods & related dependency configurations too.

                In this blog I have shared the possible scenarios, which can really help you to improve your android applications along with configurations & dependencies, which are generally missing in tutorials. This blog is helpful for beginners. As these are the issues which I faced during development & found hard to get exact solutions. 

               

• Rating Android application Programmatically 

   

     To enable rating feature in your android application You can use below code.

   gradle dependency.

   dependencies{

          implementation 'com.github.hotchemi:android-rate:1.0.1'

    }

     

@override

  protected void onCreate(@Nullable Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.main);

  AppRate.with(this).setInstallDays(1)

           .setLaunchTimes(3)

           .setRemindInterval(1)

           .monitor();

  AppRate.showRateDialogIfMeetsConditions(this);

setInstallDays(1): After Number of days(1) of installation it triggers rate dialog.

setLaunchTimes(2): It says, after launching application two times, dialog will appear.

setRemindInterval(1): if you press Remind me later. then next time rating dialog will appear after one day.

AppRate.showRateDialogIfMeetsConditions(this) :  This line calls shows rating dialog by comparing all above mentioned conditions.

• List your android application to Open_with Intent.

Edit your AndroidManifest file with blow intent inside activity tag.

<activity

    android:name=".MyActivity"

    android:label="@string/title_activity_main">

    <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" />

        <data android:mimeType="audio/*" />

    </intent-filter>

</activity>

Then in your activity class use below mentioned code:

public void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      setContentView(R.layout.main);

      Intent intent = getIntent();

      String action = intent.getAction();

      String type = intent.getType();

      if(action != null && type != null){

           Uri url = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);

             // write your code

   }

}

• Sharing File with an Intent in android using fileProvider 

   

     if you want to share file using intent in android or getting  android.os.FileUriExposedException

    if you are using targetSdkVersio >= 24 then you will have to use FileProvider. normally intent.send will not work. 

   Add a FileProvier <provider> tag in AndroidManifest.xml  under <application> tag.

   <?xml version="1.0" encoding="utf-8"?>

   <manifest xmlns:android="http://schemas.android.com/apk/res/android"

    ....

    <application

        .....

        <provider

            android:name="android.support.v4.content.FileProvider"

            android:authorities="${applicationId}.provider"

            android:exported="false"

            android:grantUriPermissions="true">

            <meta-data

                android:name="android.support.FILE_PROVIDER_PATHS"

                android:resource="@xml/provider_paths"/>

       </provider>

    </application>

  </manifest

Second step is to create provider_paths.xml file in res/xmlfolder.

And paste below content in the file.     

 <?xml version="1.0" encoding="utf-8"?>

 <paths>

    <external-path name="external_files" path="."/>

</paths>

Third Step is to write code in you java file,where you are calling method to share file.
   

     File file = new File(context.getExternalFilesDir("")+"/"+filename);

     Uri uri =  FileProvider.getUriForFile(context,context. getApplicationContext()
                                                      .getPackageName()+ ".provider", file);

     Intent shareIntent = new Intent();

     shareIntent.setAction(Intent.ACTION_SEND);

     shareIntent.putExtra(Intent.EXTRA_STREAM, uri);

     shareIntent.setType("text/*");

     shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

     startActivity(Intent.createChooser(shareIntent,"Share With..."));
