I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:
My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.
private void startCreation(){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
Uri startDir = Uri.fromFile(new File("/sdcard"));
intent.setDataAndType(startDir,
"vnd.android.cursor.dir/lysesoft.andexplorer.file");
intent.putExtra("browser_filter_extension_whitelist", "*.csv");
intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
intent.putExtra("browser_title_background_color",
getText(R.string.browser_title_background_color));
intent.putExtra("browser_title_foreground_color",
getText(R.string.browser_title_foreground_color));
intent.putExtra("browser_list_background_color",
getText(R.string.browser_list_background_color));
intent.putExtra("browser_list_fontscale", "120%");
intent.putExtra("browser_list_layout", "2");
try{
ApplicationInfo info = getPackageManager()
.getApplicationInfo("lysesoft.andexplorer", 0 );
startActivityForResult(intent, PICK_REQUEST_CODE);
} catch( PackageManager.NameNotFoundException e ){
showInstallResultMessage(R.string.error_install_andexplorer);
} catch (Exception e) {
Log.w(TAG, e.getMessage());
}
}
This methos is just pick up a dialog and if user wants install the external application from market
private void showInstallResultMessage(int msg_id) {
AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.setMessage(getText(msg_id));
dialog.setButton(getText(R.string.button_ok),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
dialog.setButton2(getText(R.string.button_install),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
startActivity(intent);
finish();
}
});
dialog.show();
}
