Android PackageInstaller：安装应用的应用，从三流Android外包到秒杀阿里P7

可以看到对application/vnd.android.package-archive这个mime的处理，还有android.intent.action.INSTALL_PACKAGE这个action的处理。

在文件管理器中点击apk文件，或者发送以上intent-filter中对应的action，就会调用PackageInstaller。

1.只安装指定前缀包名的应用

我们可以在initiateInstall()这个函数中，通过包名对将要安装的应用进行管控，参考代码如下：

private void initiateInstall() {

String pkgName = mPkgInfo.packageName;

Log.v(“AZ”,"[initiateInstall]pkgName:" + pkgName);

if(pkgName.startsWith(“com.zms”)){

// Check if there is already a package on the device with this name

// but it has been renamed to something else.

String[] oldName = mPm.canonicalToCurrentPackageNames(new String[] { pkgName });

if (oldName != null && oldName.length > 0 && oldName[0] != null) {

pkgName = oldName[0];

mPkgInfo.packageName = pkgName;

mPkgInfo.applicationInfo.packageName = pkgName;

}

// Check if package is already installed. display confirmation dialog if replacing pkg

try {

// This is a little convoluted because we want to get all uninstalled

// apps, but this may include apps with just data, and if it is just

// data we still want to count it as “installed”.

mAppInfo = mPm.getApplicationInfo(pkgName,

PackageManager.GET_UNINSTALLED_PACKAGES);

if ((mAppInfo.flags&ApplicationInfo.FLAG_INSTALLED) == 0) {

mAppInfo = null;

}

} catch (NameNotFoundException e) {

mAppInfo = null;

}

mInstallFlowAnalytics.setReplace(mAppInfo != null);

mInstallFlowAnalytics.setSystemApp(

(mAppInfo != null) && ((mAppInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0));

startInstallConfirm();

}else{

finish();

}

}

以上代码的效果就是，只安装包名以“com.zms”开头的应用。其他的不会出现安装界面，直接finish()。

2.PackageInstaller安装完某个应用，自动打开：

packages/apps/PackageInstaller/src/com/android/packageinstaller/InstallAppProgress.java

private Handler mHandler = new Handler() {

public void handleMessage(Message msg) {

switch (msg.what) {

case INSTALL_COMPLETE:

mInstallFlowAnalytics.setFlowFinishedWithPackageManagerResult(msg.arg1);

if (getIntent().getBooleanExtra(Intent.EXTRA_RETURN_RESULT, false)) {

Intent result = new Intent();

result.putExtra(Intent.EXTRA_INSTALL_RESULT, msg.arg1);

setResult(msg.arg1 == PackageManager.INSTALL_SUCCEEDED

? Activity.RESULT_OK : Activity.RESULT_FIRST_USER,

result);

finish();

return;

}

// Update the status text

mProgressBar.setVisibility(View.INVISIBLE);

// Show the ok button

int centerTextLabel;

int centerExplanationLabel = -1;

LevelListDrawable centerTextDrawable = (LevelListDrawable) getResources()

.getDrawable(R.drawable.ic_result_status);

if (msg.arg1 == PackageManager.INSTALL_SUCCEEDED) {

mLaunchButton.setVisibility(View.VISIBLE);

centerTextDrawable.setLevel(0);

centerTextLabel = R.string.install_done;

// Enable or disable launch button

mLaunchIntent = getPackageManager().getLaunchIntentForPackage(

mAppInfo.packageName);

boolean enabled = false;

if(mLaunchIntent != null) {

List list = getPackageManager().

queryIntentActivities(mLaunchIntent, 0);

if (list != null && list.size() > 0) {

enabled = true;

}

if (enabled) {

// ZMS:Add for opening app automatically START

if(mAppInfo.packageName.equals(“com.zms.demo”)){

startActivity(mLaunchIntent);

}

// ZMS:END

mLaunchButton.setonClickListener(InstallAppProgress.this);

} else {

mLaunchButton.setEnabled(false);

}

} else if (msg.arg1 == PackageManager.INSTALL_FAILED_INSUFFICIENT_STORAGE){
