This code is working fine when i select image from gallery but when i select image from download folder it give me error [java.lang.NullPointerException: Attempt to invoke virtual method 'char[] java.lang.String.toCharArray()' on a null object reference]
please help me to resolved this issue.
return Environment.getExternalStorageDirectory() + "/" + split[1]; might throw an ArrayOutOfBoundsException. Change it to
try {
return Environment.getExternalStorageDirectory() + "/" + split[1];
} catch (ArrayIndexOutOfBoundsException e) {
return Environment.getExternalStorageDirectory() + "/";
}
By the way, Could you please fill in // TODO handle non-primary volumes so that I can get the path from external storage (SD Card is what I'm after) as well?
Would you be willing to apply the Apache 2.0 license to this, like you have to several of your repositories?
for those who can't get path from sdcard, i found this solution.
