Load Images From Phone in Android by Specifying Image Path

Load Images From Phone in Android

Sample Code

private Bitmap getBitmap(String imageFilePath)
{



// Load up the image's dimensions not the image itself

BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();

bmpFactoryOptions.inJustDecodeBounds = true;

Bitmap bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);

int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight/ (float) DISPLAYHEIGHT);

int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth/ (float) DISPLAYWIDTH);

Log.v("HEIGHTRATIO", "" + heightRatio);

Log.v("WIDTHRATIO", "" + widthRatio);

// If both of the ratios are greater than 1, one of the sides of
// the image is greater than the screen


if (heightRatio > 1 && widthRatio > 1) {

if (heightRatio > widthRatio) {

// Height ratio is larger, scale according to it

bmpFactoryOptions.inSampleSize = heightRatio;

} else {

// Width ratio is larger, scale according to it

bmpFactoryOptions.inSampleSize = widthRatio;

}

}

// Decode it for real
bmpFactoryOptions.inJustDecodeBounds = false;

bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);

return bmp;
}

How to Take Screenshot Programatically in Android

 // Step1: First Create the base view

               View vi = ((ViewGroup)findViewById(android.R.id.content)).getChildAt(0);

                vi.setDrawingCacheEnabled(true);

  //   Step2: Create a Bitmap

                Bitmap b = vi.getDrawingCache();

//     step3: Save This bitmap







Convert Bitmap to Byte Array and Save

                             ByteArrayOutputStream stream = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

                             try {
OutputStream imageFileOS = getContentResolver()
.openOutputStream(imageFileUri);
imageFileOS.write(byteArray);
imageFileOS.flush();
imageFileOS.close();
} catch (FileNotFoundException e) {
} catch (IOException e) {
}
