110/17 - Android 6图片剪裁

没想到会因为图片剪裁中断，以前都偷懒使用uCrop，这次想说练习内建的剪裁，结果有够麻烦

Android 6如果要图片剪裁，路径开头是file://，所以要用Uri.fromFile()把uri转成真实路径

val intent = Intent("com.android.camera.action.CROP").apply {
    this.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION or Intent.FLAG_GRANT_READ_URI_PERMISSION)
    this.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
    this.putExtra("crop", true)
    this.putExtra("return-data", false)
    this.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString())
    this.putExtra("scale", true)
}

val cropPictureName = "005_crop_${System.currentTimeMillis()}.jpg"

val phoneFile = File(
    Environment.getExternalStoragePublicDirectory("${Environment.DIRECTORY_PICTURES}/AndroidSystem"),
    pictureName
)
val cropPhoneFile = File(
    Environment.getExternalStoragePublicDirectory("${Environment.DIRECTORY_PICTURES}/AndroidSystem"),
    cropPictureName
)


if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.M) {

    val pictureUri = Uri.fromFile(phoneFile)
    val cropUri = Uri.fromFile(cropPhoneFile)

    intent.setDataAndType(pictureUri, "image/*")
    intent.putExtra(MediaStore.EXTRA_OUTPUT, cropUri)
    Log.d("maho", "intent: $intent")
    cropPictureResultLauncher.launch(intent)
    return@registerForActivityResult
}
