@Fatehali Asamadi’s way is OK, but need to add something for appropriate use.
For Microsoft documents both (.doc or .docx), (.ppt or .pptx), (.xls or .xlsx) extensions are used. To support or browse these extensions you need to add more mimeTypes.
Use below method to browse documents where REQUEST_CODE_DOC is requestCode for onActivityResult(final int requestCode, final int resultCode,final Intent data) @Override method.
private void browseDocuments(){
String[] mimeTypes =
{"application/msword","application/vnd.openxmlformats-officedocument.wordprocessingml.document", // .doc & .docx
"application/vnd.ms-powerpoint","application/vnd.openxmlformats-officedocument.presentationml.presentation", // .ppt & .pptx
"application/vnd.ms-excel","application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", // .xls & .xlsx
"text/plain",
"application/pdf",
"application/zip"};
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
intent.setType(mimeTypes.length == 1 ? mimeTypes[0] : "*/*");
if (mimeTypes.length > 0) {
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes);
}
} else {
String mimeTypesStr = "";
for (String mimeType : mimeTypes) {
mimeTypesStr += mimeType + "|";
}
intent.setType(mimeTypesStr.substring(0,mimeTypesStr.length() - 1));
}
startActivityForResult(Intent.createChooser(intent,"ChooseFile"), REQUEST_CODE_DOC);
}
You can get clear concept and add your required mimeTypes from Here
