• Question 116:

  To build a debug APK, you can open a command line and navigate to the root of your project directory. To initiate a debug build, invoke the assembleDebug task:

  A. The file is already signed with the debug key
  B. The file is already aligned with zipalign
  C. You can immediately install this file on a device.

• Question 117:

  For example, we have a file in our raw folder app/src/main/res/raw/sample_teas.json. To get an InputStream for reading it, from out Context context, we can do this:

  A. val input = context!!.openRawResource(R.raw.sample_teas)
  B. val input = context!!.getRawResource(R.raw.sample_teas)
  C. val input = context!!.resources.openRawResource(R.raw.sample_teas)
  C. val input = context!!.resources.openRawResource(R.raw.sample_teas)

• Question 118:

  What statements about InputStreamReader (java.io.InputStreamReader) are correct? (Choose two.)

  A. An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.
  B. An InputStreamReader is a bridge from character streams to byte streams: It reads characters using a specified charset and encodes them into bytes. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.
  C. Each invocation of one of an InputStreamReader's read() methods may cause one or more bytes to be read from the underlying byte-input stream. To enable the efficient conversion of bytes to characters, more bytes may be read ahead from the underlying stream than are necessary to satisfy the current read operation.
  D. No any invocation of one of an InputStreamReader's read() methods can cause some bytes to be read from the underlying byte-input stream.
