I want to open specific path folder using Intent, I used code for File explorer and It working perfectly but in some device (samsung devices) if file explorer app are not available then It not opening folder of specific path.
I tried many solutions but It won't work for me.
Uri uri = Uri.fromFile(new File(new File(filePath).getParent()));
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "resource/folder");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setDataAndType(uri, "file/*");
startActivity(Intent.createChooser(intent, "Open folder"));
}
Here is my solution for accessing "root/Downloads/Sam" in Kotlin
val rootPath = "content://com.android.externalstorage.documents/document/primary:"
val samPath = Uri.parse("$rootPath${Environment.DIRECTORY_DOWNLOADS}%2fSam") //"%2f" represents "/"
val REQUEST_CODE_PICK_FILE = 1
main_sam_button.setOnClickListener {
val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.type = "text/plain" //specify file type
intent.putExtra(DocumentsContract.EXTRA_INITIAL_URI, samPath) //set the default folder
startActivityForResult(intent, REQUEST_CODE_PICK_FILE)
}

I have a pdf in the app's internal storage, however, I cannot open the file in the system pdf app.
val pdfDirPath = File(context.filesDir, "pdfs")
val file: File = File(pdfDirPath, "title.pdf")
val uri = Uri.fromFile(file)
val intent = Intent(Intent.ACTION_VIEW)
intent.setDataAndType(uri, "application/pdf");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
it shows the error "cannot display pdf"
Try this
Uri pdfUri = FileProvider.getUriForFile(getContext(), getContext().getApplicationContext().getPackageName() + ".provider", file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(pdfUri, "application/pdf");
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
I am trying to add option to update app by downloading apk, its getting installed successfully. But the problem is, app got close after installation, without prompting Open/Done screen in Nougat and above devices.
I have tried using both ACTION_VIEW and ACTION_INSTALL_PACKAGE, but no luck. Also tried with startActivityForResult instead of startActivity, still no luck.
public void installAPK() {
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
File file = new File(path + "update.apk");
if (Build.VERSION.SDK_INT < 24) {
intent.setDataAndType(Uri.fromFile(new File(path + "update.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
} else {
Uri apkURI = FileProvider.getUriForFile(
activity,
activity.getApplicationContext()
.getPackageName() + ".provider", file);
intent.setDataAndType(apkURI, "application/vnd.android.package-archive");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
activity.startActivityForResult(intent, RC_INSTALL_APK);
}
Anything I missed to do?
Here's sample code of my application method to open new version
void OpenNewVersion(String location) {
Intent downloadIntent;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
String PATH = Environment.getExternalStorageDirectory() + "/Download/";
File fileLocation = new File(PATH, "app-stock.apk");
Uri apkUri = FileProvider.getUriForFile(this, "Adapters.GenericFileProvider", fileLocation);
downloadIntent = new Intent(Intent.ACTION_VIEW);
downloadIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
downloadIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
downloadIntent.setDataAndType(apkUri, "application/vnd.android.package-archive");
List<ResolveInfo> resInfoList = this.getPackageManager().queryIntentActivities(downloadIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
String packageName = resolveInfo.activityInfo.packageName;
this.grantUriPermission(packageName, apkUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
} else {
File fileLocation = new File(this.getFilesDir(), "app-stock.apk");
downloadIntent = new Intent(Intent.ACTION_VIEW);
downloadIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
downloadIntent.setDataAndType(Uri.fromFile(fileLocation), "application/vnd.android.package-archive");
}
this.startActivity(downloadIntent);
}
I am generated a folder name "tesApplication" and create a file name "testFile.csc" in it and store some date into that file. Now I want to open folder dir using new intent.
I had try below code but did not work in my case any other way to achieve this.
Uri selectedUri = Uri.parse(fileNameString);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "text/csv");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}
copy this in else
public void openFolder()
{
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));
}
I appreciate your help so that my code can open a PDF file with an Intent, this is the code i have been using:
String pathFile =
Environment.getExternalStorageDirectory().toString() +
FileUtils.PATH_SEPARATOR + "myFolder" +
FileUtils.PATH_SEPARATOR + "myFile.pdf";
File pdfFile = new File( pathFile );
if ( pdfFile.exists() ) {
Uri uri = Uri.fromFile( new File( pathFile ) );
Intent intent = new Intent( Intent.ACTION_VIEW );
intent.setDataAndType(uri, "application/pdf");
intent.addFlags( Intent.FLAG_ACTIVITY_NEW_TASK );
startActivity( intent );
}
But I understand that now (from the Android-N version) the privileges are handled differently and so i hope you can help me by indicating what changes i have to make to get a PDF file opened using an Intent.
PS: In my AndroidManifest.xml I am looking for all permissions in the STORAGE:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Terrific!.
Try this code.
Intent intent = new Intent(Intent.ACTION_VIEW);
try {
String newFilePath = filePath.replaceAll("%20", " ");
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
intent.setDataAndType(Uri.parse(newFilePath), "application/pdf");
} else {
Uri uri = Uri.parse(newFilePath);
File file = new File(uri.getPath());
if (file.exists()){
uri = FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
intent.setDataAndType(uri, "application/pdf");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
}
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(intent);
What is the code to open the folder, /storge/sdcar0/0students/ to be like a screen in the picture below
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "/0students/");
intent.setDataAndType(uri, "*/*");
startActivity(Intent.createChooser(intent, "Open folder"));
I have used this code, but is not required
enter link description here
To open the directory 0students, try this.
Uri uri = Uri.parse(Environment.getExternalStorageDirectory() + "/0students/");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "resource/folder");
if (intent.resolveActivity(getPackageManager()) != null){
startActivity(intent);
}
