Errata for Hello, Android

#36185: Code example for the Android book don't render on a G1. The textures don't comply with the spec, android.png is 90x90. It should be a power of 2. 64x64 or 128x128.--Not Andy

#35570: Figure 2.3 on page 30 shows incorrect sequence of method calls between the Stopped and Running states. Specifically, it shows (1) onStart() (2) onRestart() (3) onResume().

I believe the correct sequence should be (1) onRestart, (2) onStart(), (3) onResume().

The JavaDocs in the Android SDK's onRestart() method are inconsistent on this matter, which probably explains where you got the sequence.

If you study Activity.java from the actual Android SDK source, you'll see that the final void performRestart() method actually calls callActivityOnRestart(this) followed by performStart(). This is also consistent with other parts of the SDK JavaDocs that say performRestart() is always followed by performStart(). Search for the text "always followed by " in the SDK source for Activity.java and you'll find what I'm talking about.--Eric Burke

#36219: The line reading

<uses-permission id="android.permission.RECEIVE_SMS" />

should read

<uses-permission android:name="android.permission.RECEIVE_SMS " />

#35880: one small item...

"When the player select one of the buttons on the keypad it calles the returnResult() method with the index of the button."

you should replace "index" with "index +1" or the "value of the key"--Nathan Maves

#36062: Missing code before cube.draw(gl) in drawFrame()

The cube is at this point not visible without doing something like:

gl.glMatrixMode(GL10.GL_MODELVIEW);
gl.glLoadIdentity();
gl.glTranslatef(0, 0, -3.0f);--Andreas Burø
