Saving an image from ImageView into internal storage

Question

I have created an ImageView and I can see the preview of the camera and load the captured image into the ImageView and I wanted to store the image into a directory in my internal memory. I have referred many posts and tried but I couldn't find my image in my internal memory.

This is the code I have used:

package com.example.shravan.camera;

import android.content.Context;
import android.content.ContextWrapper;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.graphics.Bitmap;
import android.graphics.drawable.BitmapDrawable;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class MainActivity extends AppCompatActivity {

    private final String TAG = "abc";

    static final int REQUEST_IMAGE_CAPTURE =1 ;
    ImageView iv;
    Uri imageUri;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button)findViewById(R.id.myB);
        iv = (ImageView) findViewById(R.id.myIV);
        //disable the button if the user has no camera
        if (!hasCamera()) {
            btn.setEnabled(false);
        }
    }

    public boolean hasCamera() {
        return getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY);
    }

    //on click event handler that launches the camera
    public void launchCamera(View v) {
        Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(i, REQUEST_IMAGE_CAPTURE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            imageUri=data.getData();
            iv.setImageURI(imageUri);;
        }
    }

    public void SaveFile(View v) {
        BitmapDrawable drawable = (BitmapDrawable) iv.getDrawable();
        Bitmap bitmap = drawable.getBitmap();

        print("Creating cw");
        ContextWrapper cw = new ContextWrapper(this.getApplicationContext());
        print("Creating dir");
        File directory = cw.getDir("ImagesDir", Context.MODE_PRIVATE);
        print("Created dir" + directory);
        File mypath = new File(directory,"myImagesDGS.jpg");
        print("path is" + mypath);

        FileOutputStream fos = null;
        try {
            print("creating fos");
            fos = new FileOutputStream(mypath);
            print("Compressing bitmap");
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                fos.close();
                print("fos closed");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    private void print(String str){
        Log.d(TAG, str);
    }

}

I have made many log messages to debug and I got one path which I couldn't find in my phone.

This is the logcat:

08-07 21:47:37.089 11030-11030/com.example.shravan.camera D/abc: Creating cw 08-07

21:47:37.089 11030-11030/com.example.shravan.camera D/abc: Creating dir 08-07

08-07 21:47:42.589 11030-11030/com.example.shravan.camera D/abc: fos closed

Is there anything I need to check and I should change? Please help!

Answer 1

Got it working!

I used this code to create a directory in my file storage and then store the image:

FileOutputStream outStream = null;

// Write to SD Card
try {
    File sdCard = Environment.getExternalStorageDirectory();
    File dir = new File(sdCard.getAbsolutePath() + "/camtest");
    dir.mkdirs();

    String fileName = String.format("%d.jpg", System.currentTimeMillis());
    File outFile = new File(dir, fileName);

    outStream = new FileOutputStream(outFile);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
    outStream.flush();
    outStream.close();

    Log.d(TAG, "onPictureTaken - wrote to " + outFile.getAbsolutePath());

    refreshGallery(outFile);
} catch (FileNotFoundException e) {
    print("FNF");
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} finally {

}

My permissions:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Finally, the most important thing:

Go to Device Settings>Device>Applications>Application Manager>"your app">Permissions>Enable Storage permission!
