How to fix android app crash issues?
Question
My project on android studio is running fine on few phones and emulators but crashes on many phones. I have a Main_Activity and clicking on login takes to a second activity. I am sharing the java files and xml files of both activities along with android manifest.
Main Activity Java file
package club.pithynews.iitbhilai_pithy;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
private EditText username;
private EditText password;
private Button login_button;
@Override
protected void onCreate(Bundle savedInstanceState) {
java.text.DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LoginButton();
}
public void LoginButton() {
username = (EditText) findViewById(R.id.editText);
password = (EditText) findViewById(R.id.editText2);
login_button = (Button) findViewById(R.id.button);
login_button.setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View v) {
if ((username.getText().toString().equals("user"))&&(password.getText().toString().equals("pass"))) {
Intent intent = new Intent("club.pithynews.iitbhilai_pithy.User");
startActivity(intent);
}
}
}
);
}
}

Error is self explanatory. You're trying to load an image that is too big.
Canvas: trying to draw too large(111300000bytes) bitmap.
One of your drawable source that you set on your ImageButton or ImageView is too big. You can:
- Scale image manually
- Perform scaling in code and set the image afterwards

java.lang.RuntimeException: Canvas: trying to draw too large(111300000bytes) bitmap.
As you can see, you are trying to display an image that is too large. Check the size of the included bitmap resources.

you are displaying an image of size 111.3 mb which is too large to handle you need to compress and scale to some smaller version before displaying. here you can scale your image.
Bitmap scaled = Bitmap.createScaledBitmap(originalBitmap, 120, 120, false);
more here and compress using
ByteArrayOutputStream out = new ByteArrayOutputStream();
scaledBitmap.compress(Bitmap.CompressFormat.JPEG, 85, out);
