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.

<pre><code>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());
 }
}
</code></pre>

This methos is just pick up a dialog and if user wants install the external application from market

<pre><code>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();
}
</code></pre>

I want to make a file uploader. And I hence I need a file chooser but I don't want to write this by myself. I find OI file manager and I think it suits me.
But how can I force user to install OI file manager?
If I cannot , is there a better way to include a file manager in my app?
Thx

Android file chooser

我想做一个文件上传器。因此我需要一个文件选择器，但我不想自己写这个。我找到了OI文件管理器，我觉得它很适合我。但是如何强制用户安装OI文件管理器？如果我不能，有没有更好的方法在我的应用程序中包含一个文件管理器？Thx
