Type safe intent building for services and activities

I was able to get static(Manifest.xml) broadcast receivers to work with IntentBuilder, but not with dynamic

registerReceiver(new MyReceiver(), new IntentFilter(MyReceiver.ACTION));
Intent intent = new MyReceiverIntentBuilder().build(this).setAction(MyReceiver.ACTION);
sendBroadcast(intent);

Could IntentBuilder be modified to accommodate for BroadcastReceivers too?

Thank you for a good library. I slightly updated the sample project.

Add DetailActivity's declaration

I got an error when I tried to launch DetailActivity.

I added declaration to the manifest file.

Set extra values corresponding to views

I succeeded to launch DetailActivity but I couldn't see any views.

It seems that all extra values are set to (TextView)findViewById(R.id.one). So I set values corresponding to views.

Given the following activity:

@IntentBuilder
public class ActivityMain extends Activity {

    @Extra
    @Optional
    public String title;

}

It generates the following builder:

public final class ActivityMainIntentBuilder {
  private String title;

  public ActivityMainIntentBuilder() {
  }

  public ActivityMainIntentBuilder title(String title) {
    this.title = title;
    return this;
  }

  public Intent build(Context context) {
    Intent intent = new Intent(context, ActivityMain.class);
    intent.putExtra("title", title);
    return intent;
  }

  public static void inject(Intent intent, ActivityMain activity) {
    Bundle extras = intent.getExtras();
    activity.title = (String) extras.get("title");
  }
}

But, when calling the method ActivityMainIntentBuilder.inject(getIntent(), this);, the application crashes on the extras.get("title") instruction because of extras nullity in the inject method.

Hi there!

I was just going to give your library a try, but soon realized that all of the generated classes are incomplete which unfortunately makes this library unusable. Basically, the processor does not set the target class to the Intent which is obviously required for it to work. Also, it is missing a Context reference.

Here's the exception:

android.content.ActivityNotFoundException: No Activity found to handle Intent { (has extras) }

And here's an example of a generated build() method using the no-arg Intent constructor:

public Intent build() {
  Intent intent = new Intent();
  intent.putExtra("userName", userName);
  return intent;
}

You can obviously work around this issue by calling [setClass(Context, Class)](http://developer.android.com/reference/android/content/Intent.html#setClass%28android.content.Context, java.lang.Class<?>%29) on the generated Intent before using it, but that kind of misses the whole point of this library in my opinion.

I might be able to send a pull request later this weekend if I don't get tied up.

Considering 2 activities like:

@IntentBuilder
public class MainActivity extends AppCompatActivity {

    @Extra
    String id;

    @Extra
    @Optional
    String title;

    // ...
}

and:

@IntentBuilder
public class SubActivity extends MainActivity {
    @Extra
    String downloadUrl;

    // ...
}

I get the following Builder:

public final class SubActivityIntentBuilder {
  private final String downloadUrl;

  public SubActivityIntentBuilder(String downloadUrl) {
    this.downloadUrl = downloadUrl;
  }

  public Intent build() {
    Intent intent = new Intent();
    intent.putExtra("downloadUrl", downloadUrl);
    return intent;
  }

  public static void inject(Intent intent, SubActivity activity) {
    Bundle extras = intent.getExtras();
    activity.downloadUrl = (String) extras.get("downloadUrl");
  }
}

Is it possible to add the support of inherited fields? So that the SubActivityIntentBuilder allows developer to manage the inherited fields id and title from MainActivity.

boolean use case, excerpt from the generated code. Don't know if this is an issue or intended, but the work-around is to use wrapper classes ex.Boolean.

public static void inject(Intent intent, MainActivity activity) {
    Bundle extras = intent.getExtras();
    if (extras.containsKey("isTablet")) {
      activity.isTablet = (boolean) extras.get("isTablet");
    } else{
      activity.isTablet = null;
    }

GitHub changed the way Markdown headings are parsed, so this change fixes it.

symbol class not found MyActivityIntentBuilder

Add check != null to intent , because if MainActivity is running in first time => Nullpointer exception

 public static void inject(Intent intent, MainActivity activity) {
    if (intent == null) return; // <---- add this line
    Bundle extras = intent.getExtras();
    if (extras.containsKey("mAppreciateSubmitted")) {
      activity.mAppreciateSubmitted = (Boolean) extras.get("mAppreciateSubmitted");
    } else {
      activity.mAppreciateSubmitted = null;
    }
  }

To fix below error:

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@allowBackup value=(false) from AndroidManifest.xml:9:9-36
    is also present at [se.emilsjolander:intentbuilder-api:0.14.0] AndroidManifest.xml:9:18-44 value=(true).
    Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:7:5-29:19 to override.

With the builder style creation of intent there is consistency. Problem is when you want do specify intent flags and actions you can no longer only builder but manual change of final intent in another static helper method.

Default values for intent flags, actions etc. in @IntentBuilder anotation would be great. Also ability to set this in builder like in: https://github.com/robertoestivill/intentbuilder

Injection is somewhat indirect way of getting extras. It is not always convenient / necessary especially if only one parameter is being passed to Activity or Service. Static accessors generated for each extra argument could be useful in aforementioned use cases.
