When I'm trying to hit the Upload button the app crashes. Dont know whats happening.Below is my MainAcyivity.java
There is also an error in the php file that shows the warning of file_put_contents. Is that related to this?
In the onClick(VIew v) method I've created a constructor of UploadImage as -- new UploadImage(image,text1.getText().toString()).execute()
public class MainActivity extends Activity implements View.OnClickListener{
private static final int RESULT_IMAGE = 1;
private static final String SERVER_ADDRESS = "http://swapnil1.host22.com/";
ImageView image1,image2;
EditText text1,text2;
Button b1,b2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
image1 = (ImageView)findViewById(R.id.image1);
image2 = (ImageView)findViewById(R.id.image2);
text1 = (EditText)findViewById(R.id.text1);
text2 = (EditText)findViewById(R.id.text2);
b1 = (Button)findViewById(R.id.button1);
b2 = (Button)findViewById(R.id.button2);
image1.setOnClickListener(this);
b1.setOnClickListener(this);
b2.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.image1:
Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i,RESULT_IMAGE);
Toast.makeText(getApplicationContext(),"Selecting Image",Toast.LENGTH_LONG).show();
break;
case R.id.button1:
Bitmap image = ((BitmapDrawable)image1.getDrawable()).getBitmap();
new UploadImage(image,text1.getText().toString());
UploadImage UI = new UploadImage();
UI.execute();
break;
case R.id.button2:
break;
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_IMAGE && resultCode == RESULT_OK && data != null)
{
Uri selectedImage = data.getData();
image1.setImageURI(selectedImage);
Toast.makeText(getApplicationContext(),"Image Selected",Toast.LENGTH_LONG).show();
}
