位图太大而无法上传到纹理

MainActivity

public class MainActivity extends AppCompatActivity {

    Button button;
    ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        button = (Button)findViewById(R.id.button);
     //   imageView = (ImageView)findViewById(R.id.imageview);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                Intent galeri_int = new Intent();
                galeri_int.setType("image/*");
                galeri_int.setAction(Intent.ACTION_GET_CONTENT);
                galeri_int.addCategory(Intent.CATEGORY_OPENABLE);


                startActivityForResult(galeri_int,44);

            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data){
      //  super.onActivityResult(requestCode,resultCode,data);
        ImageView imageview = (ImageView)findViewById(R.id.imageview);
        Bitmap bitmap = null;

        if(bitmap != null){
            bitmap.recycle();
        }

        InputStream stream = null;

        try {
            stream = getContentResolver().openInputStream(data.getData());
            bitmap = BitmapFactory.decodeStream(stream);
            stream.close();
            imageview.setImageBitmap(bitmap);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

activity_main.xml中:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="gc.uploaderimager.MainActivity">


    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="300dp"
        android:src="@drawable/abc"
        android:id="@+id/imageview"/>


    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="100dp"
        android:id="@+id/button"
        android:layout_below="@+id/imageview"
        />

</RelativeLayout>

我该如何解决这个问题?
