Taking pictures with camera on Android programmatically

Question

I have created an app with a button and wrote onClickListener for that button  I have tried several sample code examples and none of them worked  They all bring up the Android camera app and don t take photographs  I want some code which I can put in my onClickListener so when I press the button on the screen  a picture will be taken   How can I make the camera take a picture when I press a button in an Android activity

There are two ways to take a photo   1 - Using an Intent to make a photo  2 - Using the camera API  I think you should use the second way and there is a sample code here for two of them

You can use Magical Take Photo library   1  try with compile in gradle  compile  com frosquivel magicaltakephoto 1 0    2  You need this permission in your manifest xml   lt uses-permission android name  android permission WRITE EXTERNAL STORAGE   gt   lt uses-permission android name  android permission READ EXTERNAL STORAGE    gt   lt uses-permission android name  android permission CAMERA   gt    3  instance the class like this      this  is the current activity param  MagicalTakePhoto magicalTakePhoto    new MagicalTakePhoto this ANY INTEGER 0 TO 4000 FOR QUALITY     4  if you need to take picture use the method   magicalTakePhoto takePhoto  my photo name      5  if you need to select picture in device  try with the method   magicalTakePhoto selectedPicture  my header name      6  You need to override the method onActivityResult of the activity or fragment like this    Override public void onActivityResult int requestCode  int resultCode  Intent data         super onActivityResult requestCode  resultCode  data        magicalTakePhoto resultPhoto requestCode  resultCode  data            example to get photo         imageView setImageBitmap magicalTakePhoto getMyPhoto         Note  Only with this Library you can take and select picture in the device  this use a min API 15
