如何解决尝试使用ACTION_VIEW
我有一种方法可以用来从应用程序中打开文件,并且在android 10之前都可以正常工作,但是当我尝试使用google照片在android 11中打开文件时,它无法打开并显示未找到媒体吐司。我正在尝试在任何外部应用程序中打开。
这是我使用的方法:
private void openFile(String url) throws IOException {
// Create URI
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
Uri uri = Uri.parse(url);
Intent intent = null;
// Check what kind of file you are trying to open,by comparing the url with extensions.
// When the if condition is matched,plugin sets the correct intent (mime) type,// so Android knew what application to use to open the file
intent = new Intent(Intent.ACTION_VIEW);
if (url.contains(".doc") || url.contains(".docx")) {
// Word document
intent.setDataAndType(uri,"application/msword");
} else if(url.contains(".pdf")) {
// PDF file
intent.setDataAndType(uri,"application/pdf");
} else if(url.contains(".ppt") || url.contains(".pptx")) {
// Powerpoint file
intent.setDataAndType(uri,"application/vnd.ms-powerpoint");
} else if(url.contains(".xls") || url.contains(".xlsx")) {
// Excel file
intent.setDataAndType(uri,"application/vnd.ms-excel");
} else if(url.contains(".rtf")) {
// RTF file
intent.setDataAndType(uri,"application/rtf");
} else if(url.contains(".wav")) {
// WAV audio file
intent.setDataAndType(uri,"audio/x-wav");
} else if(url.contains(".gif")) {
// GIF file
intent.setDataAndType(uri,"image/gif");
} else if(url.contains(".jpg") || url.contains(".jpeg")) {
// JPG file
intent.setDataAndType(uri,"image/jpeg");
} else if(url.contains(".png")) {
// PNG file
intent.setDataAndType(uri,"image/png");
} else if(url.contains(".txt")) {
// Text file
intent.setDataAndType(uri,"text/plain");
} else if(url.contains(".mpg") || url.contains(".mpeg") || url.contains(".mpe") || url.contains(".mp4") || url.contains(".avi")) {
// Video files
intent.setDataAndType(uri,"video/*");
}
//if you want you can also define the intent type for any other file
//additionally use else clause below,to manage other unkNown extensions
//in this case,Android will show all applications installed on the device
//so you can choose which application to use
else {
intent.setDataAndType(uri,"*/*");
}
this.cordova.getActivity().startActivity(intent);
}
