最佳答案
在 android Java 上工作,最近将 SDK 更新到 API 级别29,现在有一个警告显示
在 API 级别29中不推荐使用 Environment.getExternalStorageDirectory()
我的原则是
private void saveImage() {
if (requestPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
final String folderPath = Environment.getExternalStorageDirectory() + "/PhotoEditors";
File folder = new File(folderPath);
if (!folder.exists()) {
File wallpaperDirectory = new File(folderPath);
wallpaperDirectory.mkdirs();
}
showLoading("Saving...");
final String filepath=folderPath
+ File.separator + ""
+ System.currentTimeMillis() + ".png";
File file = new File(filepath);
try {
file.createNewFile();
SaveSettings saveSettings = new SaveSettings.Builder()
.setClearViewsEnabled(true)
.setTransparencyEnabled(true)
.build();
if(isStoragePermissionGranted() ) {
mPhotoEditor.saveAsFile(file.getAbsolutePath(), saveSettings, new PhotoEditor.OnSaveListener() {
@Override
public void onSuccess(@NonNull String imagePath) {
hideLoading();
showSnackbar("Image Saved Successfully");
mPhotoEditorView.getSource().setImageURI(Uri.fromFile(new File(imagePath)));
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,Uri.fromFile(new File(filepath))));
Intent intent = new Intent(EditImageActivity.this, StartActivity.class);
startActivity(intent);
finish();
}
@Override
public void onFailure(@NonNull Exception exception) {
hideLoading();
showSnackbar("Failed to save Image");
}
});
}
还有什么别的选择吗?
