示例1: fetchPrivateKey
import android.security.KeyChain; //导入方法依赖的package包/类
private PrivateKey fetchPrivateKey(Context context, String alias) throws KeyChainException,
InterruptedException, MessagingException {
PrivateKey privateKey = KeyChain.getPrivateKey(context, alias);
if (privateKey == null) {
throw new MessagingException("No private key found for: " + alias);
}
/*
* We need to keep reference to the first private key retrieved so
* it won't get garbage collected. If it will then the whole app
* will crash on Android < 4.2 with "Fatal signal 11 code=1". See
