测试从网上下载的apk尝试装置时报错：

Performing Streamed Installadb: failed to install D:\downloads\com.qualcomm.qti.perfdump.apk: Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE: Package couldn't be installed in /data/app/com.qualcomm.qti.perfdump-FlfKF0_Q3Q3YwQaRiDAQgA==: Package com.qualcomm.qti.perfdump has no signatures that match those in shared user android.uid.shell; ignoring!]

尝试通过signapk.jar从新进行签名，报错：

java -jar signapk.jar platform.x509.pem platform.pk8 com.qualcomm.qti.perfdump.apk com.qualcomm.qti.perfdump1.apk Exception in thread "main" java.lang.UnsatisfiedLinkError: 'java.lang.String[] org.conscrypt.NativeCrypto.get_cipher_names(java.lang.String)'    at org.conscrypt.NativeCrypto.get_cipher_names(Native Method)    at org.conscrypt.NativeCrypto.<clinit>(NativeCrypto.java:764)    at org.conscrypt.OpenSSLProvider.<init>(OpenSSLProvider.java:56)    at org.conscrypt.OpenSSLProvider.<init>(OpenSSLProvider.java:49)    at com.android.signapk.SignApk.main(SignApk.java:942)

解决：

java -Djava.library.path=/home/xxx/android_dev/android/out/host/linux-x86/lib64 -jar signapk.jar platform.x509.pem platform.pk8 com.qualcomm.qti.perfdump.apk com.qualcomm.qti.perfdump1.apk

之后装置胜利：

D:\>adb install -r X:\android_dev\android\out\host\linux-x86\framework\com.qualcomm.qti.perfdump1.apkPerforming Streamed InstallSuccess

signapk源码：android/build/tools/signapk

编译实现后在android/out/host/linux-x86/framework/signapk.jar
platform.pk8和platform.x509.pem在android/build/target/product/security下：
