Android app crashes when starting a new activity via Intent

Question

Currently, I am working on my first Android application in Android Studio Code. The app consists of multiple activities. It is working beautifully on my virtual device, but the app crashes on my device when I am starting a third activity in a second activity. Thus, it is possible to go from the main activity to the second without problems.

Below you can see my class. It is important to note that, when I am running the app, I can see the toast message after the if-statement (encryptedPassword.equals(storedPassword)). After that, the app crashes. I don't see any errors. Moreover, I cannot catch the exception due the fact the app crashes before that point, obviously.

public class LoginActivity extends AppCompatActivity {

private String errorLogin;
private String wrongPassword;
private String rightPassword;
private String tryAgain;
private String greeting;
private static final String PACKAGE_NAME = "nl.test.notevault.activities";
private static final String NOTES_ACTIVITY = "NotesActivity";

Button loginButton;
EditText loginPassword;
Context context;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    loginButton = (Button)findViewById(R.id.loginButton);
    loginPassword = (EditText)findViewById(R.id.loginPassword);
    context = this;

    errorLogin = getString(R.string.error_login_general);
    wrongPassword = getString(R.string.error_login_wrong_password);
    rightPassword = getString(R.string.success_login_general);
    tryAgain = getString(R.string.action_try_again);
    greeting = getString(R.string.greeting_general);

    loginButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try {
                EncryptString e = new EncryptString();
                String encryptedPassword = e.encrypt(loginPassword.getText().toString());
                KeyValueDB k = new KeyValueDB();
                String storedPassword = k.getPassword(context);
                if (encryptedPassword.equals(storedPassword)) {
                    Toast.makeText(getApplicationContext(), rightPassword + ". " + greeting + ", " + k.getUsername(context) + "!", Toast.LENGTH_SHORT).show();
                    Intent intent = new Intent(LoginActivity.this, NotesActivity.class); 
                    startActivity(intent);
                } else {
                    Toast.makeText(getApplicationContext(), wrongPassword + ". " + tryAgain + ".", Toast.LENGTH_SHORT).show();
                    loginPassword.setText(null);
                }
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), errorLogin + ".", Toast.LENGTH_SHORT).show();
            }
        }
    });

It might be possible that something is wrong with my manifest. Below you can see it. All activities are stored in a activities package.

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".activities.MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".activities.LoginActivity"
        android:label="@string/title_activity_login" />
    <activity
        android:name=".activities.SetupActivity"
        android:label="@string/title_activity_setup" />
    <activity android:name=".activities.CreateNoteActivity" />
    <activity android:name=".activities.NotesActivity"
        android:label="Notes" />
    <activity android:name=".activities.EditNoteActivity" />
    <activity android:name=".activities.SettingsActivity"></activity>
</application>

The logcat output of the virtual device. Please note that the app is working fine on the virtual device. I cannot connect my phone to my computer due the fact I don't have the right connector atm.

The [logcat will tell you what reason your app has stopped](http://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this). Please [edit] your question with it. — OneCricketeer, Mar 04 '17 at 19:32
I have to agree with @KevinKrumwiede - a log that doesn't show the actual crash is essentially useless. — EJoshuaS - Stand with Ukraine, Mar 04 '17 at 20:50
Thanks for all replies. As aforementioned, I don't have a connector yet (USB A-USB C). Is there a way to see logs on the device itself without connecting it to a computer? It is required to enable root? — Tom, Mar 04 '17 at 21:59
try to use Splunk MINT you get all log on your mail with complete details and also its is very easy to integrate and freely available. https://docs.splunk.com/Documentation/MintAndroidSDK/5.2.x/DevGuide/Requirementsandinstallation — vijay chhalotre, Mar 05 '17 at 15:51

I bought the right cable and connected my phone to my computer. When I run the program directly in debug mode via Android Code Studio, the intent error does not pop up. I think something was wrong with my apk file, otherwise I cannot determine what the error was. Thank you all.
