Android – SendBroadcast issue inside onCLickllistener

androidbroadcastclicklistener

btn2=(Button) rowView.findViewById(R.id.button1);
    btn2.setText("Find");

      btn2.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
                    Intent Message1=new Intent();
                Message1.setAction("map");
                sendBroadcast(Message1);}

The error says the method of broadcast is undefined inside the oclicklistener. why is that?

Should be context.sendBroadcast(Intent). You can do CurrentActivity.this.sendBroadcast(Intent) Inside of OnClickListener there is no context instance that's why it cannot execute method of Context

Android – Strange OutOfMemory issue while loading an image to a Bitmap object

To fix the OutOfMemory error, you should do something like this:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
Bitmap preview_bitmap = BitmapFactory.decodeStream(is, null, options);

This inSampleSize option reduces memory consumption.

Here's a complete method. First it reads image size without decoding the content itself. Then it finds the best inSampleSize value, it should be a power of 2, and finally the image is decoded.

// Decodes image and scales it to reduce memory consumption
private Bitmap decodeFile(File f) {
    try {
        // Decode image size
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(new FileInputStream(f), null, o);

        // The new size we want to scale to
        final int REQUIRED_SIZE=70;

        // Find the correct scale value. It should be the power of 2.
        int scale = 1;
        while(o.outWidth / scale / 2 >= REQUIRED_SIZE && 
              o.outHeight / scale / 2 >= REQUIRED_SIZE) {
            scale *= 2;
        }

        // Decode with inSampleSize
        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
    } catch (FileNotFoundException e) {}
    return null;
}
