After I successfully launching the following intent:
startActivity(new Intent(Intent.ACTION_VIEW, SOME_URL));
The browser boots up fine and loads the link, but when I try to return to my app the response is sluggish. When the app eventually launches I am met with a black screen, and finally an "Application Not Responding" dialog.
No errors in logcat, no obvious memory issues, nothing to indicate what I did wrong.
The activity that launches the intent is a pretty simple activity, with one fragment:
public class LinkActivity extends AppCompatActivity {
@BindView(R.id.toolbar) Toolbar mToolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_link);
ButterKnife.bind(this);
setSupportActionbar(mToolbar);
setupActionBar();
if(savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.replace(R.id.content, LinkFragment.newInstance()).commit();
}
}
private void setupActionBar() {
ActionBar actionBar = getSupportActionBar();
if(actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowTitleEnabled(true);
}
}
}
And the fragment uses a combination of RxJava, RetroFit and Dagger ‡ to load a list of links:
public class LinkFragment extends Fragment {
@Inject RestService mRestService;
@BindView(R.id.recycler) RecyclerView mRecyclerView;
public static LinkFragment newInstance() {
return new LinkFragment();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_link, container, false);
Injector.getContextComponent().inject(this);
ButterKnife.bind(this, view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getContext());
mRecyclerView.addItemDecoration(new DividerDecoration(getContext());
mRecyclerView.setAdapter(new LinkAdapter(new ArrayList<>()));
mRestService.getLinks()
.subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(this::onNext, this::onError);
return view;
}
private void onNext(Response<Link> response) [
LinkAdapter adapter = new LinkAdapter(response.data());
adapter.setOnItemClickListener(this::onItemSelected);
mRecyclerView.swapAdapter(adapter, false);
}
private void onError(Throwable throwable) {
Timber.w(throwable, "Failed to obtain links");
}
private void onItemSelected(int position, View view, Link link) {
startActivity(new Intent(Intent.ACTION_VIEW, link.getUri());
}
}
