• Utilize the https://knowledge.udacity.com/ forum to seek help on content-specific issues.
• Submit a support ticket along with the link to your forked repository if (learners are) blocked for other reasons. Here are the links for the retail consumers and enterprise learners.

Miwok App

This app displays lists of vocabulary words for the user to learn the Miwok language. Used in a Udacity course in the Beginning Android Nanodegree.

How to use this repository

• Fork this repository to your Github account.
• Open Android Studio 3.2.x+ in your local machine.
• We recommend you to use the Version Control System(VCS) in your Android Studio 3.2.x+ IDE to clone the repository directly in your IDE.
• You may have to use the File > Settings > Version Control (VCS) menu option to set up Git settings.
• Refer to this IntelliJ document for details.
• Working with VCS will make it easy for you to push your updates or switch between branches to your remote repository in Github.

Prerequisites

• Android Studio 3.2.1 or higher
• compileSdkVersion 32 (For AndroidX dependencies, the min compileSdkVersion version is 31)
• minSdkVersion 21
• Supports up to Android 12
• Gradle 7.2.0

To run app in an Android Virtual Device (AVD), we have used the following configuration:

• Pixel 4 Mobile device with x86 System image
• API level 30
• Android 11

Note - Gradle Updates

The Android Studio build system depends on Gradle and its plugins. The Gradle and its plugins have to be updated separately of Android Studio. For the updated version, refer to the following updated files: ~/build.gradle (project) file ~/app/build.graddle(: app) file ~/gradle/wrapper/gradle-wrapper.properties file You can refer anytime to the latest Android Gradle plugin release notes for the newest version of plugins.

This sample uses the Gradle build system. To build this project, use the "gradlew build" command or use "Import Project" in Android Studio.

Troubleshoot

• Gradle version and Android Gradle Plugin version should be compatible. See the table here
• Sometimes, if you face unexpected behavior, go to File > Invalidate Caches/Restart.
• Android Studio - How to Change Android SDK Path?
• In case you face some unexpected errors with the Emulator, it will be beneficial to wipe out the AVD data by going to Tools >> Device Manager >> Select Device >> Wipe out option.

cannot resolved NumbersActivity

getting bytecode to dec and null point exception errors

Error:Error converting bytecode to dex:

cant run apps, Look in Screenshot.

PhrasesActivity is broken

After i put the audio file IDs, The Layout is no longer showing the text views. but the audio plays. Seems to me like the new objects are confused by the resource IDs (as in, they cannot figure out whether the third inputs are images or audio files since they are both int type and image input comes before audio input.

audioResourceId cannot be resolved

I had an error that couldn't find the audioResourceId and tried many things, reading the code over and over again...

Tutorial Codes Pre-written!

On importing this file, i found out that most of the upcoming tutorial's code is already inside mainActivity.java/also the 4 activities were already included.

error

Cannot run program "git.exe": CreateProcess error=2, The system cannot find the file specified

Setting.jar not found

hey guys i am facing the same problem it say cannot find settings. jar and i cant understand what is the mean by removing the build file and perform clean project

A different approach

I just tried to use the WordAdapter alone to also pick up audio resources for the currentWord as well as managing AudioFocus. This way I never really needed to modify all the category activities (NumbersActivity, FamilyActivity, etc…).

Setting.jar file not found

Hi Team
when downloaded project zip file, and trying to import, then getting message "can not find file" " setting.jar" file is not found.

any input ?

Shouldn't {@link ...} tag be used inside a JavaDoc comment?

I saw these tags inside regular comments here, Shouldn't those tag be inside a JavaDoc comment to work? Something like the following format for example.

/**
* {@link android.widget.ArrayAdapter}
*/

Can not open the project

I tried many ways to open the project, but none of them works with me. I stuck in "Building 'Miwok' Gradle project info! I been looking for many solution online for this is problem but none of them solve my problem. Pleas help me!

why it take so long for building the project ?

i download this then import this project in android studio but it just loading saying that "Building miwok gradle project info".

my environment is :
windows 10. android studio 2.3

not working at all

I feel silly.

Where is the zip file option?

Unfortunately, Miwok has stopped.

After putting the "releaseMediaPlayer()" method on the category (such as in NumbersActivity), after clicking any of the word, instead of playing the audio - the app is unfortunately closing. Without this method. the app is running fine. What's the problem can be?

Gradle Build Taking too long after adding Images

Gradle Build is taking too long after I added the images and updated the Java files and the WordAdapter.
It's currently 21 minutes as I am writing this since I clicked on the run App button. I've lost all hope that the Gradle Build will finish this year.

Before these changes, Gradle Build usually finished in about 2-3 minutes.

What to do?

Gradle Sync Error .

position varable

I have problem with this line position variable

Word word = words.get(position);

error: cannot find symbol variable position

I use the MediaPlayer class in WordAdapter

` //Set the audio from the resource ID

    final MediaPlayer mediaPlayer = MediaPlayer.create(getContext(), currentWord.getAudioResourceId());

    textContainer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mediaPlayer.start();// no need to call prepare(); create() does that for you

        }
    });

    // Return the whole list item layout (containing 2 TextViews) so that it can be shown in
    // the ListView.
    return listItemView;
}

}`

Project Not Importing Properly

Hello,

When I execute the following steps in Android Studio,

**Steps:

1. Open Android Studio

2. Click Import project

3. Set Path to Extracted Project Directory

4. Choose "Import project from external model" and select "Gradle"

5. Hit "Next"

6. Set Gradle project: (Path to Extracted Project Directory)

7. Click radio button with text "Use local gradle distribution"

8. Set Gradle home: C:/Program Files/Android/Android Studio/gradle/gradle-3.2

9. Set Project format: .idea (directory based)

10. Hit "Finish"**

---

I receive the message:

"Frameworks detected: Android framework is detected in the project Configure"

---

I've looked around quite a bit to find solutions to this import, but there has been no success.
I've attached two screenshots of the current SDK manager specs/versions.

Any assistance would be appreciated. Thank you.

App closes upon updating the NumbersActivity

What am I doing wrong? I have updated the complete NumbersActivity, following the show me the answer clip, but it doesn't resemble the final code, nor does it work. I had a crash upon opening the NumbersActivity which I solved with an If statement mMediaPlayer != null and now I can open the activity, but no sound plays and hitting it a couple of times, it shuts down.

Below my code:

package com.example.android.miwok;

import android.content.Context;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import android.widget.ListView;
import java.util.ArrayList;

public class NumbersActivity extends AppCompatActivity {

// Handles playback of all the sound files
private MediaPlayer mMediaPlayer;
//Handles audio focus when playing a sound file

private AudioManager.OnAudioFocusChangeListener mOnAudioFocusChangeListener =

            @Override

                    /* The AUDIOFOCUS_LOSS_TRANSIENT case means we've lost audio focus for a
                    * short amount of time. The AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK case means
                    * our app is allowed to continue playing sound but at a lower volume. We want
                    * both cases the same way because our app is playing short sound files.*/
                    // Pause playback and reset player.
                    mMediaPlayer.pause();
                    // To restart the audiofile from the beginning, instead of resume playback
                    mMediaPlayer.seekTo(0);

                } else if (focusChange == AudioManager.AUDIOFOCUS_GAIN) {

No XML and gradle not running

I have spent 2 hours trying to fix this and I'm at a complete loss as to what to do...
I have updated Android Studio and it still doesn't work.

I unzip the zipped folder. I import a project. I select the imported project.

The next bit frustrates me because there are a tonne of options and stages to go through and no where is there any indication of how to navigate this. Most of the terminology is completely new to me but it is assumed I should understand it.

Anyway,I import from a file (rather than externally). I then leave it at 1.8SDK although I also attempted the other options.

When the project loads up it says it isn't running gradle and all internet instructions on how to address this, including the Android page do not seem to be having this issue.
There is also no xml visible, only java
The java also has many errors
There is also no way of running the app

Please help me get past these issues?!!!
Thank you
Ed

Having issue importing file

So i followed direction of the video, and I imported the file into Android Stuido, but I am unable to run the app and I get a gradle not synced issue... I tried multiple time to resolve the issue and I also deleted files and re-imported the file and still get same issues. Assistance would be greatly appreciated.

For some reason everytime I download the zip file and try to open it up in android studio I get
"Cannot import anything from C:/Users/Anghel/Downloads/ud839_Miwok-Starter-code.zip"

Play one audio song

When I clicked any item of listview to star the song, it couldn't play it. The songs are in the raw directory of res. How can I solve the problem?

Also, the icon of song file shows "?" , What does it mean?

Maybe, it can cause the volume to 0

Here is the code below.

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
           @Override
           public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
               //Toast.makeText(NumbersActivity.this,"List Item Clicked",Toast.LENGTH_SHORT).show();
               mediaPlayer = MediaPlayer.create(NumbersActivity.this, R.raw.number_one);
               mediaPlayer.start(); // no need to call prepare(); create() does that for you

           }
       });
