Android应用生死轮回的那些事儿(6) - 武器库完结篇
Android应用生死轮回的那些事儿(6) - 武器库完结篇
PackageManager武器库的完结篇，让我们梳理一下从Android 1.0到Android 7.0的发展过程吧。
资源相关API
这些API虽然数量众多，但是功能相对简单，都是根据包头或者是ApplicationInfo或Activity信息去获取一些资源，如图标，文本等。
Android 1.0创始API
- getXml：获取xml
- getText:从资源中读取文本
- getResourcesForApplication(app)：获取资源对象
- getResourcesForApplication(appPackageName)：获取资源对象
- getResourcesForActivity：从Activity中获取资源对象
- getDrawable：获取Drawable
- getDefaultActivityIcon:Activity的默认Icon
- getApplicationLabel:获取Applicaiton的标签
- getApplicationIcon：获取图标
- getActivityIcon：获取图标
Android 2.3新增API
Android 2.3新增两个API，都是跟Logo相关。
- getApplicationLogo
- getActivityLogo
Android 4.4手表版新增API
手表上新增了Banner.
- getApplicationBanner
- getActivityBanner
Android 5.0新增API
Android 5.0新增了UserBadged UI，所以新增了三个方法：
- getUserBadgedLabel
- getUserBadgedIcon
- getUserBadgedDrawableForDensity
禁掉或者解禁相关API
Android中可以支持将应用或者组件禁掉或者解禁。
ComponentEnableSetting是通过组件名来设置，ApplicationEnableSetting是通过包名。
- setComponentEnabledSetting
- getComponentEnabledSetting
- setApplicationEnabledSetting
- getApplicationEnabledSetting
setApplicationEnabledSetting
原型：
void setApplicationEnabledSetting (String packageName, int newState, int flags)参数：
- 包名
- 新状态：状态请见下面的3种。
- 标志位：要么是DONT_KILL_APP，要么是0.
状态可以为：
- COMPONENT_ENABLED_STATE_ENABLED
- COMPONENT_ENABLED_STATE_DISABLED
- COMPONENT_ENABLED_STATE_DEFAULT
例程：禁掉微信：
public void testSetApplicationEnableSetting() {
mPm.setApplicationEnabledSetting("com.tencent.mm", PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
}setComponentEnabledSetting
将包中的四大组件之一禁掉或解禁。
原型：
void setComponentEnabledSetting (ComponentName componentName, int newState, int flags);参数与上面的针对整个应用的一致。
检查签名
Android 1.0时，只能检查两个包名的签名是否一致。
原型：
int checkSignatures (String pkg1, String pkg2);到了Android 2.0，也可以支持对两个uid之间判断签名。
问题是，从包名获取uid的API，要到Android 7.0才有呢。。。
原型：
int checkSignatures (int uid1, int uid2);Prefer相关
addPackageToPreferred API已经在Android 2.1被除名，所以Prefer相关的API，只剩下下面三个：
- getPreferredPackages
- getPreferredActivities
- clearPackagePreferredActivities
至此，Android 1.0的PackageManager提供的46个API全部讲完了。
feature相关API
Android 2.0开始引入feature的概念。我们可以通过getSystemAvailableFeatures方法获取系统支持哪些feature. 或者是通过hasSystemFeature(name)方法判断是否支持一个feature.
不过，Android 2.0的时候，feature是不分版本号的。支持版本号的或者是通过hasSystemFeature方法要到Android 7.0才会出品。
FeatureInfo类
属性：
- flags: FLAG_REQUIRED或0
- name:属性名
- reqGlEsVersion:在name为空时，为需要的OpenGL ES的版本号
- version:(Android 7.0才有)版本号
方法：
- getGlEsVersion(): 0x00010002代表1.2
getSystemAvailableFeatures
原型：
FeatureInfo[] getSystemAvailableFeatures ();例程：
public void testGetSystemAvailableFeatures(){
final FeatureInfo[] fis = mPm.getSystemAvailableFeatures();
if(fis!=null){
for(FeatureInfo fi:fis){
Log.d(TAG,"Feature Info:"+fi.toString());
}
}
}输出结果：
