android.content.res.Resources $ NotFoundException API等级19 _resources

知识的价值不在于占有，而在于使用。这篇文章主要讲述android.content.res.Resources $ NotFoundException API等级19相关的知识，希望能为你提供帮助。
有人知道为什么当我在android 7上测试我的apk完美，测试5完美...但如果我测试4.4.2崩溃加载图标来自drawable ...这是我的apk崩溃的代码：

Drawable drawable = null; Integer id_icon = 0; if (materia.getIcon() != null) { id_icon = getResources().getIdentifier(materia.getIcon(), "drawable", "com.package"); } else { Integer size = materia.getTopics().size(); if (size > = 1 & & size < = 9) { id_icon = getResources().getIdentifier("ic_filter_" + size.toString() + "_black", "drawable", "com.package"); } else { if (size > 9) { id_icon = getResources().getIdentifier("ic_filter_9_plus_black", "drawable", "com.package"); } } } //This line is where throw the exception.... but why?? if (id_icon > 0) drawable = (Drawable) getResources().getDrawable(id_icon); MenuItem menuItem = sm.add(R.id.list_materiales, Menu.NONE, i, html.fromHtml(materia.getMaterial())).setCheckable(true).setChecked(false); menuItem.setIcon(drawable); storageKeys.addKeyMaterial(materia.getKey());

这是我的gradle conf：

apply plugin: 'com.android.application' apply plugin: 'realm-android'android { compileSdkVersion 26 defaultConfig { applicationId "com.package" minSdkVersion 19 targetSdkVersion 19 versionCode 1 versionName "1.0" vectorDrawables.useSupportLibrary = true } buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro' } } compileOptions { targetCompatibility 1.8 sourceCompatibility 1.8 } } dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') implementation 'com.android.support:cardview-v7:26.1.0' implementation 'com.android.support:recyclerview-v7:26.1.0' // implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support:design:26.1.0' implementation 'com.android.support.constraint:constraint-layout:1.0.2''com.android.support.test.espresso:espresso-core:+' implementation 'com.android.support:support-v4:26.1.0' implementation 'com.android.support:support-vector-drawable:26.1.0' }

先谢谢了...抱歉我的英语不好......
答案你在使用矢量绘图吗？
如果有的话请参考这篇文章。
