Problem when receiving, via Intent, a file shared by another app

Question

I’m having trouble opening the shared file via Intent. I can properly receive the path to the file but mine app closes the execution. And unfortunately I’m not able to capture the error generated. My code:

    @Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Intent intent = getIntent();
    String action = intent.getAction();
    String type = intent.getType();
    Log.d("Artur", "Action: "+action);
    Log.d("Artur", "Type: "+type);

    if (Intent.ACTION_SEND.equals(action) && type != null) {
        if ("*/*".equals(type)) {
            Uri arqUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
            if (arqUri != null) {
                try {
                    FileInputStream fis;
                    Log.d("Artur", "vai abrir: "+arqUri.getPath());
                    fis = openFileInput(arqUri.getPath());  //<----ERRO
                    Log.d("Artur", "Leu: "+(byte)fis.read());

                    fis.close();

                } catch (FileNotFoundException e) {
                    Log.d("Artur", "FileNotFoundException");
                    e.printStackTrace();
                    return;
                } catch (IOException e) {
                    Log.d("Artur", "IOException");
                    e.printStackTrace();
                    return;
                }
            }
        }
    } else {
        // Handle other intents, such as being started from the home screen
        //Toast.makeText(getApplicationContext(),"Arquivo nao identificado", Toast.LENGTH_SHORT).show();
    }

I also have another question. I can only receive a file if the "share with" option is used in the calling app. I would like my program to become the standard for opening this type of file, which has the RLC extension, for example: "config.rlc". So just set it as default to read this file, when receiving one by email or other source would just a tap on it for my program to run. As it is with a text editor, pdf, image viewer and others. Thank you.

Edited.

I solved the opening problem, typing error:

Fis = new Fileinputstream(arqUri.getPath());

But now I’m trying file error does not exist.

Edited: I managed to solve the second part of my problem. That block was missing:

            <intent-filter>
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <data android:mimeType="*/*"/>
            <data android:pathPattern=".*\\.rlc" />
        </intent-filter>

Now continue with the file problem does not exist.

                    Uri arqUri = intent.getData();

                Log.d("Artur", "arqUri: " + arqUri);
                if (arqUri != null) {
                    try {
                        FileInputStream fis;
                        String caminho = arqUri.getPath();
                        Log.d("Artur", "Caminho: " + caminho);
                        File file = new File(caminho);
                        fis = new FileInputStream(file);

                        Log.d("Artur", "Leu: " + (byte) fis.read());

                        fis.close();

                    } catch (FileNotFoundException e) {
                        Log.d("Artur", "FileNotFoundException");
                        e.printStackTrace();
                        //return;
                    } catch (IOException e) {
                        Log.d("Artur", "IOException");
                        e.printStackTrace();
                        //return;
                    }
                }

Answer 1

In this code exposed it seems that is missing, at least, the request for reading in the storage of the device, because otherwise will always occur the permission error. Following is suggested correction:

// Storage Permissions variables
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE
};

    //persmission method.
     public static void verifyStoragePermissions(Activity activity) {
        // Check if we have read or write permission
        int writePermission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        int readPermission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.READ_EXTERNAL_STORAGE);

        if (writePermission != PackageManager.PERMISSION_GRANTED || readPermission != PackageManager.PERMISSION_GRANTED) {
            // We don't have permission so prompt the user
            ActivityCompat.requestPermissions(
                    activity,
                    PERMISSIONS_STORAGE,
                    REQUEST_EXTERNAL_STORAGE
            );
        }
    }
