Android apk安装的几种方法

1.使用linux命令安装：

apk事先保存在sdcard上面，如果安装不成功，可能权限不够，chmod 777一下，问题就解决了。

try {
String cmd = "pm install -r sdcard/TestStartActivity_sig2.apk";
Runtime.getRuntime().exec(cmd);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

2.使用adb命令安装。

am start -n 包名/Activity所在包名及类名

adb shell am start -n com.liusl.test/com.liusl.test.MainActivity

3.使用发送Intent消息打开apk安装程序

public void installApk(String saveFileName) {
File apkfile = new File(saveFileName);
if (!apkfile.exists()) {
Log.i(TAG, "installApk..file not exist!" + apkfile);
return;
}
Intent i = new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.parse("file://" + apkfile.toString()),"application/vnd.android.package-archive");
mContext.startActivity(i);
}

4.静默安装：安装过程中没有任何提示的安装

[1] 重写pacakgemanager的相关类

IPackageDateObserver.java ,IPackageDeleteObserver.java,IPackageInstallObserver.java,IPackageMoveObserver.java,IPackageStateObserver.java,PackageManager.java

[2] 注册消息接收类

private static BroadcastReceiver mPackageInstallReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(UpdateManager.PACKAGE_INSTALL_SUCC)) {
Log.i(TAG, " receive .PACKAGE_INSTALL_SUCC");
} else {
Log.i(TAG, " receive .PACKAGE_INSTALL_FAILED.");
}
}
};

[3] 安装apk发送消息

private boolean installApkDefault(Context context, String fileName, String packageName) {
Log.d(TAG, "installApkDefault:" + packageName + ",fileName:" + fileName);
File file = new File(fileName);
int installFlags = 0;
if (!file.exists())
return false;
installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;
PackageManager pm = context.getPackageManager();
try {
IPackageInstallObserver observer = new MyPakcageInstallObserver(context, fileName,packageName);
Log.i(TAG, "installFlags:" + installFlags + "packagename:" + packageName);
pm.installPackage(Uri.fromFile(file), observer, installFlags, packageName);
return true;
} catch (Exception e) {
Log.e(TAG, "installApkDefault fail ;exception: " + e.getMessage());
}
return false;
}

private class MyPakcageInstallObserver extends IPackageInstallObserver.Stub {
Context cxt;
String filename;
String pkname;
public MyPakcageInstallObserver(Context c, String filename, String packagename) {
this.cxt = c;
this.filename = filename;
this.pkname = packagename;
}
@Override
public void packageInstalled(String packageName, int returnCode) {
Log.i("MyPakcageInstallObserver", "returnCode = " + returnCode);// 返回1代表安装成功
if (pkname != null && pkname.equals(packageName)) {
Intent it = new Intent();
it.putExtra("install_returnCode", returnCode);
it.putExtra("install_packageName", packageName);
if (returnCode == 1) {
it.setAction(UpdateManager.PACKAGE_INSTALL_SUCC);
} else {
it.setAction(UpdateManager.PACKAGE_INSTALL_FAILED);
File f = new File(filename);
if (f.exists()) {
f.delete();
}
}
cxt.sendBroadcast(it);
}
}

}
