裁剪意图在 Android Studio 中不起作用

Question

I have a problem regarding cropping image in android studio, whenever I run this cropping code on my device or any other One-plus device, it runs efficiently. But other devices like Redmi, Samsung, Motorola, crash after reaching this cropping part. if I comment out the function call to the cropping function, it runs smoothly on all devices but at cost of non-availability of cropping

public void ImageCropFunction(Uri uri) {

        // Image Crop Code
        try {
            Intent CropIntent = new Intent("com.android.camera.action.CROP");
            Toast.makeText(getContext(),"plz, Crop the Required part",Toast.LENGTH_LONG).show();
            CropIntent.setDataAndType(uri, "image/*");
            CropIntent.putExtra("crop", "true");
            CropIntent.putExtra("outputX", 1024);
            CropIntent.putExtra("outputY", 1024);
            CropIntent.putExtra("return-data", true);
            CropIntent.putExtra("return-uri", uri.toString());
            startActivityForResult(CropIntent, 222);
        }catch (ActivityNotFoundException e) {
        }
    }

Answer 1

Android does not have a CROP Intent . There is no requirement for any device to support that undocumented Intent , let alone with those undocumented extras. There are dozens of libraries for image cropping . Please use one.

Answer 2

What to use

---

You can use uCrop library.

Implemention

---

Make sure you have this line in your settings.gradle

maven { url "https://jitpack.io" }

Add it to your build.gradle .

implementation 'com.github.yalantis:ucrop:2.2.6'

Then you should add it to your manifest

<activity
    android:name="com.yalantis.ucrop.UCropActivity"
    android:screenOrientation="portrait"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

How to use

---

You can crop a image like this

UCrop.of(yourImageUri, whereToSaveYourCroppedImageUri)
    .withAspectRatio(16, 9) // you can change the aspect ratio.
    .withMaxResultSize(maxWidth, maxHeight) // you can add a custom result height for the image. eg 512 X 512
    .start(context); // enter the context and the crop will start.

Get the result

---

You can fetch the result in the onActivityResult like this

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK && requestCode == UCrop.REQUEST_CROP) {
        final Uri resultUri = UCrop.getOutput(data);
        // crop is successful
    } else if (resultCode == UCrop.RESULT_ERROR) {
        final Throwable cropError = UCrop.getError(data);
        // crop failed
    }
}
