Получение исключения Nullpointer после обновления до Android design support 22.2.1

Question

Получение исключения Nullpointer после обновления до Android design support 22.2.1

Мой проект работал нормально непосредственно перед обновлением до Android design support 22.2.1, после обновления и запуска программы я получаю ошибку ниже. исключение не говорит, какая строка в коде или файле java вызывает ошибку, поэтому не знаю, какой код опубликовать . похоже, это какая-то внутренняя ошибка поддержки дизайна android.

Моя активность расширяется AppCompatActivity и мое тестовое устройство API 15(Android 4.04).

Я использую NavigationView и DrawerLayout в своем коде.

Мой построить.gradle

android {
compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "com.stackoverflow.ranjith.androidprojdel"
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.+'
compile 'com.parse.bolts:bolts-android:1.+'
compile 'com.android.support:cardview-v7:22.2.+'
compile 'com.android.support:recyclerview-v7:22.2.+'
compile 'com.google.android.gms:play-services-plus:7.5.0'
compile 'com.google.android.gms:play-services-ads:7.5.0'
compile 'com.android.support:design:22.2.+'
compile 'joda-time:joda-time:2.8.1'
}

Исключение:

Обновить

Когда я откатываюсь к 22.2.0, ошибка исчезает, не знаю, в чем проблема.

2 6

android androiddesignsupport nullpointerexception appcompat-v7-r22.2

2 ответа:

У меня была та же проблема, и я смог избежать ее с помощью этого кода:
View header = LayoutInflater.from(this).inflate(R.layout.nav_header_main, null);
navigationView.addHeaderView(header);
TextView text = (TextView) header.findViewById(R.id.textView);
texto.setText("HELLO");

Проблема связана с xml-меню NavigationView.

Мой выглядит так:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
            android:id="@+id/navigation_subheader"
            android:title="Titulo">
        <menu>
            <item
                    android:id="@+id/navigation_sub_item_1"
                    android:icon="@drawable/abc_btn_radio_material"
                    android:title="sub-1"/>
            <item
                    android:id="@+id/navigation_sub_item_2"
                    android:icon="@drawable/abc_btn_rating_star_on_mtrl_alpha"
                    android:title="sub-2"/>
        </menu>
    </item>
</menu>

Но если я переключаюсь на значок проекта, который можно нарисовать, он фиксируется:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
            android:id="@+id/navigation_subheader"
            android:title="Titulo">
        <menu>
            <item
                    android:id="@+id/navigation_sub_item_1"
              ----> android:icon="@drawable/some_local_drawable"
                    android:title="sub-1"/>
            <item
                    android:id="@+id/navigation_sub_item_2"
              ----> android:icon="@drawable/some_local_drawable"
                    android:title="sub-2"/>
        </menu>
    </item>
</menu>

Конечно, это происходит после обновления до 22.2.1
